DrmGpu::updateOutputs is now changing the state of some drm properties
without changing the fitting output state (namely RenderLoop inhibition)
which can lead to rendering being inhibited indefinitely in some cases
Software-based clipping is naive. It maps the clip region from the
global screen coordinates and intersects it with window quads. If the
window is transformed, the quads won't be clipped as expected.
Unfortunately, the OpenGL scene enables software-based geometry clipping
if the screen transformed. It's not clear why it does so, perhaps as a
performance optimization? Either way, this produces incorrect results
when the screen is scaled.

This makes ExpoLayout easier to maintain. As is, the main issue with it
is the number of layout algorithms.
With this, the ExpoLayout is going to have two layout algorithms - one is
very simple and the other not so.
Startup code in plasmashell was changed so xsetroot is not called
anymore, which is sort of fine.
Unfortunately (or not?), it exposed a bug in kwin. Cursor::x11Cursor()
only works in the standalone X11 session.
On Wayland, Cursor::x11Cursor() will return XCB_NONE which results in
seeing cross cursor when there should be arrow cursor.
This change moves xcb_cursor_t look up code from X11Cursor to the base
Cursor class. In hindsight, I would like to introduce a window manager
class where the xcb cursor and other x11 specific code can be moved in
the future for better encapsulation of platform-specific code.

For some reason, layers are change after applying Show Desktop effect, so
we will have AboveLayer for our popups and Desktop, and NotificationLayer
for Dock which hides us.
Also, OSD and critical notifications were always hidden by our popups.
This patch solves both the issues.
Usual notifications will still be hidden, but hopefully it's not a big
issue.
BUG: 442605
reinterpret_cast<>() will fail if the types we cast from and to have
mismatching sizes.
Unfortunately, there are platforms that have Window and
EGLNativeWindowType of different size. This results in compilation
errors.
In order to work around those problematic platforms, this change
replaces reinterpret_cast cast with a c style cast.
EffectQuickView is used by Aurorae. As long as Aurorae decorations are
rendered by kwin, it's not a problem. However, kde-gtk-config kded
module can also render them. This creates a problem. If effects object
is not created, accessing any of its getters or setters will result in a
segmentation fault.
This change rewrites the share context check so the effects object is
not accessed anymore.
One could argue that kde-gtk-config has to provide a dummy EffectsHandler
but it doesn't use effects and libkwineffects is not a dependency of
KDecoration2. So, providing a dummy EffectsHandler makes no sense.
In hindsight, we need to revisit the usage of EffectQuickView in Aurorae
as accessing the EffectsHandler in EffectQuickView is a totally valid
usecase and integration of QOpenGLContext.

When running in plasma, the animation speed slider is in General
Behavior KCM.
The Defaults button should not reset the animation speed slider because
it's hidden.
BUG: 442600
With per-screen rendering, the projection matrix is no longer created
with the workspace geometry, i.e. all screen geometries united, so the
center of the workspace geometry may not map to (0, 0) in the clip
coordinates.
GLRenderTarget::virtualScreenGeometry() can be used to query the rect
that was used to create the projection matrix.
BUG: 442770
KMS can only ever have one frame pending at the moment. If we
update the outputs while a pageflip is still pending on any output
the atomic commit will fail with EBUSY, which both invalidates
the testing for output configuration and makes applying the wanted
configuration fail.
This can be removed again once KMS gains the ability to do mailbox
presentation; that will likely still take a while though.
BUG: 442677
Currently, data from client buffer EGLStream is copied to a surface
texture. An fbo is used for that purpose. The main issue with it is that
it doesn't restore the old framebuffer binding.
The surface texture can be updated in the middle of a compositing cycle.
If the framebuffer binding is not restored, any window that must be
rendered in an offscreen texture won't be rendered to the offscreen
texture.
This change makes EglStreamSurfaceTextureWayland restore the fbo binding
so the DeformEffect and software screen rotation work as expected with
the proprietary NVIDIA driver.
BUG: 442697
This makes the compositingPossible() output more elaborative,
and adjusts their priorities to qCWarning.
I thought about dropping the "Compositing is not possible"
(qCCritical) message. It's not critical for X11 and Wayland
depends on OpenGL. OTOH it's from a different component. So in
the end I settled for qCWarning again; there is no real way
to know, if the platform will consider this a critical problem
(and eventually abort).
Then I saw X11StandalonePlatform::compositingNotPossibleReason,
which has more user friendly, QT Richtext / HTML encoded output,
but this seems overkill for the terminal; now I would like to
know, where this is actually used...
While at it report "manually" suspended compositing via qCInfo
instead of qCDebug.
After updating my Debian buster to bullseye, I noticed missing
shadows / composite for KDE, which made overlapping windows hard
to recognize.
.xsession-errors just had "kwin_core: Compositing is not possible".
Using the suggested QT_LOGGING_RULES="kwin_*.debug=true" didn't
provide any more clues; nothing I tried did.
Eventually I ended reading the kwin source and found, that
disabled composite via kwinrc :: [Compositing] :: OpenGLIsUnsafe
was not reported.
IMHO all these disabling cases should use qCCritical(KWIN_CORE),
like the "Compositing is not possible" message, but for the time
being, this simply logs the OpenGLIsUnsafe reason, just like all
the others.
With the recent AbstractOutput changes, Workspace::clientArea() overload
that takes only the window and no additional output was changed to
return clientArea(opt, window, window->output());
prior to that, it had been looking up the output at the center of the
frame geometry.
As it turns out, AbstractOutput::sendToOutput() blocks geometry updates,
which in its turn means that Toplevel::output() will be updated only
after geometry updates are unblocked. For the most part, it's not a big
deal until you need to use Workspace::clientArea(opt, const Toplevel*)
Since the output won't be updated until geometry updates are unblocked,
clientArea(opt, const Toplevel *) may return outdated info.
One could argue that we just simply need to update m_output similar to
m_frameGeometry when geometry updates are blocked, but... it's not going
to work on wayland! On Wayland, GeometryUpdatesBlocker is totally
unnecessary. Even if a window is resized, m_frameGeometry will be left
unchanged until the client repaints the window.
Instead, one need to pass the AbstractOutput to clientArea() if it's
important.
This change makes X11Client::changeMaximize() query the MaximizeArea of
the output containing the center of the move resize geometry, similar to
what the XdgToplevelClient does.
BUG: 442534
There are some unresolved issues where driving outputs can fail because
of bandwidth constraints. These don't appear to happen with implicit
modifiers, or at least they don't happen as often.
libinput will send release and proximity out events after the device is
disconnected.
This just takes into account that tablet might be nullptr.
BUG: 442573
The stored geometry is irrelevant in the window is maximized.
This is especially relevant if we:
* open a virtual keyboard
* rotate the display (then it looks ok as it was already addressed)
* then remove the keyboard.
At that point we want to reset to the available area rather than the
previous.
By supporting all the required attributes in the DecorationThemeMetaData class
the custom struct can be dropped.

We can just put the parameter in the variant list. Because the method is virtual, the keyword
parameter must exist in the method definition.

b38bb416 introduced flicker when restarting compositing because the
DrmGpu::findWorkingCombination method usually creates new buffers for
the commit, without rendering into them. Instead of that, re-use
existing buffers where possible
