This change ensures that KWin can be built with a version of KWS that

I didn't backport KWINDOWSYSTEM_BUILD_DEPRECATED_SINCE macro because
the next release of Plasma (5.18) depends on KF 5.66.

212d87a32e [scenes/opengl] Remove outdated hack to reset vertex buffers
Summary:
Scene opengl has a callback for when we have a GL error. One of the
handlers for an error calls scheduleVboReInit the history shows it was a
forerunner to the GLX_NV_robustness_video_memory_purge but resetting
only one tiny part based on debug output.

When we get here we schedule a reset of the vertex buffer, via a timer.
When the timer is caled we have no idea what GL context was last
current, if it's not the currect context then the main scene
GLVertexBuffer will be deleted but not correctly re-initialised.

We have two very common crashes with a corrupted
GLVertexBuffer::streamingBuffer() which would match up perfectly.

Given that we now have a proper mechanism to reset the entire scene, we
don't need this timer based hack and resolve that problem.

af71763be5 [scene] Fix decoration texture bleeding
Summary:
Quite long time ago, window decorations were painted on real X11 windows.
The nicest thing about that approach is that we get both contents of the
client and the frame window at the same time. However, somewhere around
KDE 4.2 - 4.3 times, decoration rendering architecture had been changed
to what we have now.

I've mentioned the previous decoration rendering design because it didn't
have a problem that the new design has, namely the texture bleeding issue.

In the name of better performance, opengl scene puts all decoration parts
to an atlas. This is totally reasonable, however we must be super cautious
about things such as the GL_LINEAR filter.

The GL_LINEAR filter may need to sample a couple of neighboring texels
in order to produce the final texel value. However, since all decoration
parts now live in a single texture, we have to make sure that we don't
sample texels that belong to another decoration part.

This patch fixes the texture bleeding problem by padding each individual
decoration part in the atlas. There is another solution for this problem
though. We could render a window into an offscreen texture and then map
that texture on the transformed window geometry. This would work well and
we definitely need an offscreen rendering path in the opengl scene,
however it's not feasible at the moment since we need to break the window
quads API. Also, it would be great to have as less as possible stuff going
on between invocation of Scene::Window::performPaint() and getting the
corresponding pixel data on the screen.

There is a good chance that the new padding stuff may make you vomit. If
it does so, I'm all ears for the suggestions how to make the code more
nicer.

d1cfcf4c97 Avoid texture bleed rendering X11 window
Summary:
We currently see a gap on transformed windows between the window and the
top decoration.

This is partly the atlas bleed on the decoration, and partly a bleed on
the window content itself.

On X11, the window we composite is the frame window - which is a larger
texture containing a transparent border where the frame normally would
be. When we sample with a linear filter we include these texels. Hence
GL_CLAMP_TO_EDGE doesn't work.

Vlad's patch to composite the correct window, not the frame was my
preferred approach, but we had to revert it as it caused an issue with
xwayland :(

Half pixel correction nearly worked, but caused blurry fonts.

This patch resolves it in the fragment shader used by effects doing
transforms. We pass the real texture geometry of the window to the
client with a half pixel correction. Any samples outside the outer half
pixel are then clamped within bounds.

Arguably a hack, but solves the problem in a comparatively
non-invasive way.

BUG: 360549
BUG: 257566

Test Plan:
X11:
Using Vlad's atlas padding for decoration
Slowed animations, wobbled a dark window over a light background
No artifacts

Wayland:
This isn't needed. Now tested that everything still renders the same.

1e3128b0db Flexible composite swap and timer events
Summary:
The GLX backend might need a combination of swap and composite timer events for
continous painting.

The reason for that is that if the buffer age extension is not available we
fall back to copies in case not the whole screen is repainted.

The timer logic is adapted to make this possible in a lean way what cleans up
the Compositor class in several ways.

Test Plan: Tested on X11 (with/without swap events, buffer age enabled)  and Wayland.

1a13015d2d Possible fix for KDecoration crash in systemsettings
Summary:
I could never reproduce the crash, but we know from gdb that it's from
the decorationSettings object

We are setting the same QObject instance as a context property in
multiple contexts at once. This is already slightly odd especially from the POV of
Qt's internal property cache.

Given we want one object to be exposed to all contexts, we can expose it
to the parent context only once and achieve the same result in a simpler
way.

BUG: 411166

Verified opening and closing system settings still worked for me.

When initializing a property we loop through the drmModeObjectProperties
object and search for the property by its name.

Once found we create the Property object and there should be not another one
with the same name afterwards. In any case we would leak memory. Therefore just
directly return once the property was found.

This gives us the added benefit that we can put out a warning in case the
property was not found in the loop, what should not happen with the properties

754b72d155 [x11] Name client pixmap instead of frame pixmap
Summary:
Since KDE 4.2 - 4.3 times, KWin doesn't paint window decorations on real
X11 windows, except when compositing is turned off. This leaves us with
a problem. The actual client contents is inside a larger texture with no
useful pixel data around it. This and decoration texture bleeding are
the main factors that contribute to 1px gap between the server-side
decoration and client contents with effects such as wobbly windows, and
zoom.

Another problem with naming frame pixmap instead of client pixmap is
that it doesn't quite go along with wayland. It only makes more difficult
to abstract window quad generation in the scene.

Since we don't actually need the frame window when compositing is on,
there is nothing that holds us from redirecting client windows instead
of frame windows. This will help us to fix the texture bleeding issue
and also help us with the ongoing redesign of the scene.

Test Plan: X11 clients are still composited.

9d4a32596c Drop some custom list typedefs
Summary:
Qt has its own thing where a type might also have corresponding list
alias, e.g. QObject and QObjectList, QWidget and QWidgetList. I don't
know why Qt does that, maybe for some historical reasons, but what
matters is that we copy this pattern here in KWin. While this pattern
might be useful with some long list types, for example

    QList<QWeakPointer<TabBoxClient>> TabBoxClientList

in general, it causes more harm than good. For example, we've got two
new client types, do we need corresponding list typedefs for them? If
no, why do we have ClientList and so on?

Another problem with these typedefs is that you need to include utils.h
header in order to use them. A better way to handle such things is to
just forward declare a client class (if that's possible) and use it
directly with QList or QVector. This way translation units don't get
"bloated" with utils.h stuff for no apparent reason.

So, in order to make code more consistent and easier to follow, this
change drops some of our custom typedefs. Namely ConstClientList,
ClientList, DeletedList, UnmanagedList, ToplevelList, and GroupList.

Test Plan: Compiles.

84d75cb567 [x11] Add support for _GTK_FRAME_EXTENTS
Summary:
KDE is known for having a strong view on the client-side decorations vs
server-side decorations issue. The main argument raised against CSD is
that desktop will look less consistent when clients start drawing window
decorations by themselves, which is somewhat true. It all ties to how
well each toolkit is integrated with the desktop environment.

KDE doesn't control the desktop market on Linux. Another big "player"
is GNOME. Both KDE and GNOME have very polarized views on in which
direction desktop should move forward. The KDE community is pushing more
toward server-side decorations while the GNOME community is pushing
more toward client-side decorations. Both communities have developed
great applications and it's not rare to see a GNOME application being
used in KDE Plasma. The only problem is that these different views are
not left behind the curtain and our users pay the price. Resizing GTK
clients in Plasma became practically impossible due to resize borders
having small hit area.

When a client draws its window decoration, it's more likely that it also
draws the drop-shadow around the decoration. The compositor must know
the extents of the shadow so things like snapping and so on work as
expected. And here lies the problem... While the xdg-shell protocol has
a way to specify such things, the NetWM spec doesn't have anything like
that. There's _GTK_FRAME_EXTENTS in the wild, however the problem with
it is that it's a proprietary atom, which is specific only to GTK apps.

Due to that, _GTK_FRAME_EXTENTS wasn't implemented because implementing
anything like that would require major changes in how we think about
geometry.

Recent xdg-shell window geometry patches adjusted geometry abstractions
in kwin to such a degree that it's very easy to add support for client
side decorated clients on X11. We just have to make sure that the
X11Client class provides correct buffer geometry and frame geometry when
the gtk frame extents are set.

Even though the X11 code is feature frozen, I still think it's worth
to have _GTK_FRAME_EXTENTS support in kwin because it will fix the resize
issues. Also, because KWin/Wayland is unfortunately far from becoming
default, it will help us with testing some implementation bits of the
window geometry from xdg-shell.

BUG: 390550
FIXED-IN: 5.18.0

Test Plan:
Things like quick tiling, maximizing, tiling scripts and so on work as
expected with GTK clients.

fb2d4c113f Adjust scene for client-side decorated clients
Summary:
Currently our Scene is quite naive about geometry. It assumes that the
window frame wraps the attached buffer/client. While this is true for X11
clients, such geometry model is not suitable for client-side decorated
clients, in our case for xdg-shell clients that set window geometry
other than the bounding rectangle of the main surface.

In general, the proposed solution doesn't make any concrete assumptions
about the order between frame and buffer geometry, however we may still
need to reconsider the design of Scene once it starts to generate quads
for sub-surfaces.

6bfa931f2b Associate output transforms and orientations
Summary:
We use internally Qt:ScreenOrientation for representing output transforms.

This is not ideal since the values do not map directly to Wayland transform
values, but we can make it work by using OR combinations of
Qt:ScreenOrientations.

Do this for now and see if we should not better introduce an internal enum
mapped directly.

Additionally the OR combinations need to be handled in the drm backend at
various places accordingly as well (see TODOs).

8d13729031 [platforms/x11] Never block on retrace, always present after paint
Summary:
Compositing in X11 was done time shifted, meaning that we paint first, then
wait one vblank interval length and present on prepareRenderingFrame the
previous paint result. This is supposed to make sure we don't miss the vblank
and in case of block till retrace be able to continue issuing commands and
only shortly before next vblank present.

This is counter-intuitiv, not how we do it on Wayland or even on MESA with X.
The reason seems to be that the GLX backend was in the beginning written
against Nvidia proprietary driver which needed this but nowadays even this
driver defaults to non-blocking behavior on buffer swap.

Therefore remove this legacy anomaly fully and directly present after paint.
We then wait one refresh cycle and in the future can optimize this by delaying
the paint and present till shortly before vsync.

Test Plan: kwin_x11 tested on i915 and Nvidia proprietary driver.

Summary:
Selecting not to vsync does not make sense for an X11 compositor. In the end
we want clients to be able to present async if they want to but the compositor
is supposed to send swaps with vsync to the XServer in order to not generate
tearing artifacts.

There was also a detection logic which did some questionable things in case
vsync was not available. I don't think this is necessary at all since we can
just always run a timer to present with or without vsync.

ad892ce3a6 [platforms/x11] Remove triple buffering detection
Summary:
It is not clear what the advantage of triple buffering is for KWin. An X11
compositor is meant to swap buffers once every monitor cycle. For that triple
buffering is not necessary.

The functionality is not maintained, does not reliably work as displayed by
the existence of an environment variable to force some behavior, pollutes
our code and every compositing-related problem that might be mitigated with
triple buffering should find a simpler and more fitting solution with other
means.

There is one caveat which is if we shall block for retrace. We set it
currently according to the result of the swap profiler and in the most common
case with double buffering it is set to true. But on Nvidia systems this might
be actual the wrong behavior. Instead of trying to work around this ignore
the issue for now and move the overall architecture to something less complex
by presenting after paint how we do it in the Wayland DRM backend and with
double buffering on GLX (although this is at the moment also borken because
we actually present then twice).

Test Plan: kwin_x11 tested on i915.

DecorationOptions has a pointer to the previously set decoration which
is now dangling, and we crash.

Rather than adding more guards and smart pointers in DecorationOptions,
this patch deletes the QQmlContext before deleting the context
properties that we expose.

It also moves unreferring the shared qmlcontext we inherit from till
after we've deleted the child context, because it didn't make sense.

This change renames the geometry property to frameGeometry in order to
reflect the new meaning assigned to it as well to make it easier to

40b0296d5c [libkwineffects] Introduce API to easily show a QtQuick scene in an effect
Summary:
EffectQuickView/Scene is a convenient class to render a QtQuick
scenegraph into an effect.

Current methods (such as present windows) involve creating an underlying
platform window which is expensive, causes a headache to filter out
again in the rest of the code, and only works as an overlay.

The new class exposes things more natively to an effect where we don't
mess with real windows, we can perform the painting anywhere in the view
and we don't have issues with hiding/closing.

QtQuick has both software and hardware accelerated modes, and kwin also
has 3 render backends. Every combination is supported.

* When used in OpenGL mode for both, we render into an FBO export the
texture ID then it's up to the effect to render that into a scene.

* When using software QtQuick rendering we blit into an image, upload
that into a KWinGLTexture which serves as an abstraction layer and
render that into the scene.

* When using GL for QtQuick and XRender/QPainter in kwin everything is
rendered into the internal FBO, blit and exported as an image.

* When using software rendering for both an image gets passed directly.

Mouse and keyboard events can be forwarded, only if the effect
intercepts them.

The class is meant to be generic enough that we can remove all the
QtQuick code from Aurorae.

The intention is also to replace EffectFrameImpl using this backend and
we can kill all of the EffectFrame code throughout the scenes.

The close button in present windows will also be ported to this,
simplifiying that code base.

Classes that handle the rendering and handling QML are intentionally
split so that in the future we can have a declarative effects API create
overlays from within the same context. Similar to how one can
instantiate windows from a typical QML scene.

Notes:
I don't like how I pass the kwin GL context from the backends into the
effect, but I need something that works with the library separation. It
also currently has wayland problem if I create a QOpenGLContext before
the QPA is set up with a scene - but I don't have anything better?

I know for the EffectFrame we need an API to push things through the
effects stack to handle blur/invert etc. Will deal with that when we
port the EffectFrame.

Test Plan: Used in an effect

3ba33e4b58 Use lambdas for queued invocation of composition suspending
Summary:
Qt's metaobject is rather sensitive with scope resolution.

Foo::Bar and Bar don't always match to a Qt metaobject, even if they
refer to the same thing to a compiler. Here we register
X11Compositor::SuspendReason but Q_ARG uses SuspendReason and they don't
match. This leads to a runtime failure where the method isn't invoked.

Rather than fixing metaobject usage, port the whole thing to lambdas
which does better compile time checking and is generally nicer to read.

ffcbe24e2b Rename Client to X11Client
Summary:
Currently each managed X11 client is represented with an instance of
Client class, however the name of that class is very generic and the
only reason why it's called that way is because historically kwin
was created as an x11 window manager, so "Client" was a sensible choice.

With introduction of wayland support, things had changed and therefore
Client needs to be renamed to X11Client in order to better reflect what
that class stands for.

Renaming of Client to X11Client was agreed upon during the last KWin
sprint.

Test Plan: Compiles, the test suite is still green.

bebe81209c Port QPA away from Wayland
Summary:
So far wayland was used by internal clients to submit raster buffers
and position themselves on the screen. While we didn't have issues with
submitting raster buffers, there were some problems with positioning
task switchers. Mostly, because we had effectively two paths that may
alter geometry.

A better approach to deal with internal clients is to let our QPA use
kwin core api directly. This way we can eliminate unnecessary roundtrips
as well make geometry handling much easier and comprehensible.

The last missing piece is shadows. Both Plasma::Dialog and Breeze widget
style use platform-specific APIs to set and unset shadows. We need to
add shadows API to KWindowSystem. Even though some internal clients lack
drop-shadows at the moment, I don't consider it to be a blocker. We can
add shadows back later on.

62a7db7028 Use nullptr everywhere
Summary:
Because KWin is a very old project, we use three kinds of null pointer
literals: 0, NULL, and nullptr. Since C++11, it's recommended to use
nullptr keyword.

This change converts all usages of 0 and NULL literal to nullptr. Even
though it breaks git history, we need to do it in order to have consistent
code as well to ease code reviews (it's very tempting for some people to
add unrelated changes to their patches, e.g. converting NULL to nullptr).

Test Plan: Compiles.

Introduce environment variable, which when used, will make it possible

df3c1de848 [platforms/drm] Rework enablement and dpms switching
Summary:
This patch further refines output management.

We go now through AbstractWaylandOutput virtual functions to enable and
disable outputs.

Dpms changes and enablement switches use separate code paths at start in the
Drm backend code since they are similar but not the directly same. Common code
is shared though, functions are renamed accordingly.

Asserts have been put in place to better understand and check the control
flow. A seemingly unnecessary call to DrmOutput::pageFlipped on reactivation
after Vt switch has been removed to allow for that.

In future patches we need to look additionally at the legacy mode switching
code path which was and is still not working and better handling of the
current monitor Dpms state. For example a monitor being switched off is not
properly acted on and the workspace still expanded.

Test Plan:
With one and two monitors:
* Dpms off/on
* Vt switches
* Screen disable/enable

of Platform into a Wayland child class like for AbstractOutput.

So far we were following a bit unique and rare doxygen comment style:

Doxygen comments with this style look balanced and neat, but many people
that contribute to KWin don't follow this style. Instead, they prefer
more traditional doxygen comment style, i.e.

    /**
     * Contents of the comment.
     */

Reviewing such changes has been a bit frustrating for me (so selfish!)
and for other contributors.

This change switches doxygen comment style in KWin to a more traditional
style. The main reason for doing this is to make code review process easier
for new contributors as well us.

8af2fa73dc Run clang-tidy with modernize-use-override check
Summary:
Currently code base of kwin can be viewed as two pieces. One is very
ancient, and the other one is more modern, which uses new C++ features.

The main problem with the ancient code is that it was written before
C++11 era. So, no override or final keywords, lambdas, etc.

Quite recently, KDE compiler settings were changed to show a warning if
a virtual method has missing override keyword. As you might have already
guessed, this fired back at us because of that ancient code. We had
about 500 new compiler warnings.

A "solution" was proposed to that problem - disable -Wno-suggest-override
and the other similar warning for clang. It's hard to call a solution
because those warnings are disabled not only for the old code, but also
for new. This is not what we want!

The main argument for not actually fixing the problem was that git
history will be screwed as well because of human factor. While good git
history is a very important thing, we should not go crazy about it and
block every change that somehow alters git history. git blame allows to
specify starting revision for a reason.

The other argument (human factor) can be easily solved by using tools
such as clang-tidy. clang-tidy is a clang-based linter for C++. It can
be used for various things, e.g. fixing coding style(e.g. add missing
braces to if statements, readability-braces-around-statements check),
or in our case add missing override keywords.

Test Plan: Compiles.

or utilize a surfaceless context extension. For the sake of simplicity
this change sticks with pbuffers, but it's a good idea to support both
methods.

c898f96df3 [platforms/drm] EGLStream DRM Backend Initial Implementation
Summary:
This is the initial implementation of a DRM backend based on the EGLDevice,
EGLOutput, and EGLStream extensions, supporting NVIDIA graphics hardware using
their proprietary driver. The new backend will be used if the environment
variable KWIN_DRM_USE_EGL_STREAMS is set. On initialization, it will attempt to
create an EGLDevice based on the DRM device currently in use and create
EGLOutputs and EGLStreams for any attached displays. These are used to control
presentation of the final composited frame. Additionally, it will register the
wl_eglstream_controller Wayland interface so that native EGL windows created by
clients can be attached to an EGLStream allowing buffer contents to be shared
with the compositor as a GL texture.

At this time there are two known bugs in the NVIDIA driver's EGL implementation
affecting desktop functionality. The first can result in tooltip windows drawn
by plasmashell to contain incorrect contents. The second prevents KWayland from
being able to query the format of EGLStream-backed buffers which interferes
with the blur effect. Fixes for both of these are currently in development and
should appear in an upcoming NVIDIA driver release.

Additionally, hardware cursors are currently not supported with this backend.
Enabling them causes the desktop to intermittently hang for several seconds.
This is also likely a bug in the NVIDIA DRM-KMS implementation but the root
cause is still under investigation.

Test Plan:
On a system with an NVIDIA graphics card running a recent release of their
proprietary driver

    * Ensure the nvidia_drm kernel module is loaded with the option "modeset=1"
      ("# cat /sys/module/nvidia_drm/parameters/modeset" should print "Y")
    * Ensure EGL external platform support is installed
      https://github.com/NVIDIA/eglexternalplatform
    * Ensure KWin was build with the CMake option
      KWIN_BUILD_EGL_STREAM_BACKEND=ON (this is the default)
    * Start a plasma wayland session with the environment variable
      KWIN_DRM_USE_EGL_STREAMS set
    * Ensure output from KWin OpenGL initialization indicates the NVIDIA EGL
      driver is in use (as opposed to Mesa / llvmpipe).
    * Desktop should be fully functional and perform smoothly.

a1e8541b49 [qpa] Don't specify EGL_SURFACE_TYPE when choosing EGLConfig
Summary:
Since QPA only performs off-screen rendering, it does not require an EGLConfig
that supports any particular surface type.  Currently it requests a config
supporting window surfaces, however the EGLDeviceEXT platform, which is the
basis of the EGLStream back-end used with the proprietary NVIDIA driver, does
not support such surfaces resulting in eglChooseConfig not returning any valid
configs when that back-end is in use. Since QPA doesn't actually create any
window surfaces, it should be fine to remove this restriction to allow it to
initialize properly with the EGLStream back-end.

22a441e071 [platforms/x11] Force glXSwapBuffers to block with NVIDIA driver
Summary:
The NVIDIA implementation of glXSwapBuffers will, by default, queue up
to two frames for presentation before blocking. KWin's compositor,
however, assumes that calls to glXSwapBuffers will always block until
the next vblank when rendering double buffered. This assumption isn't
valid, as glXSwapBuffers is specified as being an implicit glFlush,
not an implicit glFinish, and so it isn't required to block. When this
assumption is violated, KWin's frame timing logic will
break. Specifically, there will be extraneous calls to
setCompositeTimer with a waitTime of 0 after the non-blocking buffer
swaps, dramatically reducing desktop responsiveness. To remedy this,
a call to glXWaitGL was added by Thomas Luebking after glXSwapBuffers
in 2015 (see bug 346275, commit
8bea96d701). That glXWaitGL call is
equivalent to a glFinish call in direct rendering, so it was a good
way to make glXSwapBuffers behave as though it implied a glFinish
call.

However, the NVIDIA driver will by default do a busy wait in glFinish,
for reduced latency. Therefore that change dramatically increased CPU
usage. GL_YIELD can be set to USLEEP (case insensitive) to change
the behavior and use usleep instead. When using the NVIDIA driver,
KWin will disable vsync entirely if GL_YIELD isn't set to USLEEP
(case sensitive, a bug in KWin).

However, the NVIDIA driver supports another environment variable,
__GL_MaxFramesAllowed, which can be used to control how many frames
may be queued by glXSwapBuffers. If this is set to 1 the function
will always block until retrace, in line with KWin's expectations.
This allows the now-unnecessary call to glXWaitGL to be removed along
with the logic to conditionally disable vsync, providing a better
experience on NVIDIA hardware.

7b13393b64 [platforms/wayland] Multi output support
Summary:
This patch rewrites large parts of the Wayland platform plugin, in order to
facilitate the testing of multi output behavior in nested KWin sessions.

For that a new class WaylandOutput is introduced, which is based on
AbstractOutput and by that shares functionality with our virtual and DRM
platform plugins.

The EGL/GBM and QPainter backends have been remodelled after the DRM one,
sharing similiarities there as well now.

Pointer grabbing has been rewritten to support multiple outputs, now using
pointer locking instead of confining and drawing in this case onto a sub-
surface, which get dynamically recreated in between the different output
surfaces while the cursor is being moved.

Window resizing is possible if host supports xdg-shell, but currently the
mode size does not yet fill the new window size.

The number of outputs can be set by command line argument `--output-count`,
scaling is also supported by setting the argument `--scale`.

Further steps could be:
* Enabling automatic fill of resized windows via Wayland mode change
* Multiple diverging initial sizes and scale factors for mulitple outputs

**Watch it in action:** https://youtu.be/FYItn1jvkbI

Test Plan: Tested it in live session.

and drmModeMoveCursor functions will still be unnecessarily called when the
cursor is moved or hidden.

To correct this, SceneOpenGL should connect Platform::cursorChanged as opposed
to Cursor::cursorChanged to its texture update function, as only the former
will be emitted when the cursor is updated and the compositor should check if
the cursor is hidden and the software cursor image is not null before rendering
it. DrmBackend::moveCursor and DrmBackend::hideCursor should also return
immediately if using a software cursor.

Summary:
My change in 304528e80b has been reported to
cause issues for PostMarketOS https://gitlab.com/postmarketOS/pmaports/issues/204
I originally submitted the change to activate Framebuffer devices
as secondary framebuffer devices are not on by default, (such as a
secondary DisplayLink device). Changing attributes usually forced
some framebuffer devices to turn on, however I have found a more
accurate way to turn on framebuffer devices, without messing with
the color layout.

38e22ce6d1 [platforms/x11] Properly unload effects on X11
Summary:
When Compositor finishes compositing, it destroys EffectsHandlerImpl,
which in its turn tries to unload all effects. But there is a problem...

EffectsHandlerImpl has platform-specific hooks to ungrab keyboard and
also stop mouse interception. Given that any call made to a virtual function
in the destructor of a base class(EffectsHandlerImpl) won't go to a derived
class(EffectsHandlerImplX11), keyboard won't be ungrabbed even if effect
that grabbed it is already gone.

We can't discard Deleted before EffectsHandler is destroyed because

On the other hand, the fact that Deleted may outlive scene doesn't
make sense because Deleted exist purely for animation purposes and
nothing more.

This change arranges lifetime of Deleted so it's more reasonable.

cbbe94d769 Restrict available supported compositors based on first initialized one
Summary:
On Wayland we cannot switch from OpenGL to QPainter compositor as this
would break any running OpenGL application. KWin registers it's
EGLDisplay to Wayland and without OpenGL this doesn't make sense any
more. We are not able to render OpenGL buffers in the QPainter
compositor.

While it's theoretically possible to switch from QPainter to OpenGL it
doesn't make any sense for the same reason. Any running OpenGL
application would be using llvmpipe and could not be switched to proper
OpenGL.

This change stores the selected compositing type in Platform and the
implementations can use it to restrict the supported compositors. On X11
we don't need this, all other Platforms implement the restriction. Thus
it's no longer possible to switch the backends at runtime.

Test Plan:
Adjusted tests run, no runtime test as gui doesn't support
switching to QPainter anyway.

e48d9df14f [qpa] Drop PlatformContextWayland which uses wayland egl for OpenGL
Summary:
Using the Wayland protocol for OpenGL is no longer used or useful. KWin
internal windows only use OpenGL through QtQuick. We either have the
sharing context (KWin uses OpenGL for compositing) or we have the
QPainter compositor which also turns QtQuick to use software renderer.

Thus a situation where the Wayland platform context is useful doesn't
exist any more. Removing it helps getting the QPA plugin Wayland free.

Test Plan:
Run nested KWin triggering Outline once with OpenGL and once
with QPainter compositor.

3dc22d7d88 [platforms/hwcomposer] Add scaling support
Summary:
Despite plasma frameworks doing it's own scaling with fonts, it's been
requested to use kwin/wayland scaling.

Like DRM, when kscreen is not used, scale value is loaded from a config
file.

Config format is
[HWComposerOutputs][0]
Scale=N

The 0 is to map similarly to DRM and support multi-screen, but with a
screen index
rather than a UUID based on EDID.

Because we don't support multi screen this is always 0 for now.

Test Plan: Ran with the config value unset and with the config value at
Scale=3.

02a0561016 Add windowsystem plugin for KWin's qpa
Summary:
KWindowSystem provides a plugin interface to have platform specific
implementations. So far KWin relied on the implementation in
KWayland-integration repository.

This is something I find unsuited, for the following reasons:
 * any test in KWin for functionality set through the plugin would fail
 * it's not clear what's going on where
 * in worst case some code could deadlock
 * KWin shouldn't use KWindowSystem and only a small subset is allowed
to be used

The last point needs some further explanation. KWin internally does not
and cannot use KWindowSystem. KWindowSystem (especially KWindowInfo) is
exposing information which KWin sets. It's more than weird if KWin asks
KWindowSystem for the state of a window it set itself. On X11 it's just
slow, on Wayland it can result in roundtrips to KWin itself which is
dangerous.

But due to using Plasma components we have a few areas where we use
KWindowSystem. E.g. a Plasma::Dialog sets a window type, the slide in
direction, blur and background contrast. This we want to support and
need to support. Other API elements we do not want, like for examples
the available windows. KWin internal windows either have direct access
to KWin or a scripting interface exposed providing (limited) access -
there is just no need to have this in KWindowSystem.

To make it more clear what KWin supports as API of KWindowSystem for
internal windows this change implements a stripped down version of the
kwayland-integration plugin. The main difference is that it does not use
KWayland at all, but a QWindow internal side channel.

To support this EffectWindow provides an accessor for internalWindow and
the three already mentioned effects are adjusted to read from the
internal QWindow and it's dynamic properties.

This change is a first step for a further refactoring. I plan to split
the internal window out of ShellClient into a dedicated class. I think
there are nowadays too many special cases. If it moves out there is the
question whether we really want to use Wayland for the internal windows
or whether this is just historic ballast (after all we used to use
qwayland for that in the beginning).

As the change could introduce regressions I'm targetting 5.16.

Test Plan:
new test case for window type, manual testing using Alt+Tab
for the effects integration. Sliding popups, blur and contrast worked fine.

5d63b9c05b Fix flickering with Qt 5.12
Summary:
Mesa requires XESetWireToEvent xlib callbacks to be called
when DRI2 is used. This is done by the GLX integration in
the Qt's xcb plugin, but Qt 5.12 initializes the GLX integration
only when required, e.g. when a window with OpenGL support is
created or when availability of OpenGL is checked.

So force initialization of the GLX integration by calling
QOpenGLContext::supportsThreadedOpenGL().

Summary:
So far we didn't try to do high DPI on kwin internal windows, such as

Due to wayland scaling they were the correct phyiscal size but upscaled.
This patch fixes our QPA to enable Qt's high-dpi support.

BUG: 402853

Note icons are still low res. This is because the global
QGuiApplication::devicePixelRatio which is the max of all connected
screens is static for the duration of the app. QIcon uses this when
determining the DPR to use. This will require a Qt change.

* Tab switcher is high DPI
* Overlay in present windows Desktop grid are still ok

 * pass through --args command line argument
 * use dbus call to already open kcm

Neither of the two ways is working. The kwincompositing doesn't parse
the arguments and the dbus interface doesn't exist any more.

Following the advice to remove functionality nobody noticed that it is
broken, this is removed with this change. This probably broke with
introducing the new KCM which happened IIRC for Plasma 5.0.

21aee588af Initialize Wayland output in AbstractOutput
Summary:
Wayland output is on protocol level and not dependent on the hardware
platform. Next steps are to do the same for output device and then let
the virtual output call into these initializing functions as well.

Test Plan: Manually and auto test.

54eb3bf137 Copy the aurorae decoration qml plugin to bin dir in build directory
Summary:
Look there, another plugin I didn't remember. The other qml files are
not needed for the aurorae autotest as it's for the svg based themes
instead of qml themes like Plastik.

Test Plan: Further destroyed my system, test failed, with this change passed.

456cbb9bf7 Remove unused private Qt include
Summary:
Ideally KWin would not depend on private headers... but at least we can
remove unused ones.

Test Plan: still builds, I don't see anything requiring the header.

6724955a76 [qpa] Always keep a at least one screen
Summary:
Qt does not like having no screens. Both Qt XCB and Wayland QPAs have
systems pretend there's always at least 1 screen
present.

Kwin already uses a dummy screen on startup, this patch reinserts the
dummy screen if the platform states that all real screens are removed.

BUG: 399564

Test Plan:
Logged in, everything still worked
Did not reproduce the original bug

6ebfa59331 [plugins/qpa] Don't crash on Qt5.12 OpengGL::makeCurrent
Summary:
QOpenGLContext was changed to call platform->makeCurrent before it
called setCurrentContext.

Because we bind window FBO and ultimately that calls
QOpenGlContext::format we need Qt to know which context is current so it
can tell us the format.

This matches the QtWayland EGL code.

BUG: 399392

Test Plan:
Switched virtual desktop with the OSD (previously reliably crashed)
Now it doesn't
