Change the default value from "Do Not Affect" to "Apply Initially" when
adding new properties in Window Rules.
REASON: prior "Do Not Affect" as default and occasionally I forget to
change the setting to something else when adding new properties.
Unfortunately, this means I forget to do it and so it isn't saved when
I close the window. I will then go back in to change it to Apply Initially
or in some cases have to add the new property again as it wasn't saved in
the set.
I think if Apply Initially were to be the default it would be an easier
and faster experience to add new properties.
Change the setting's type from `QString` to `QStringList`
and adjust relevant code.
Previous config requires no porting as a single string in the
config file is read as the first item in the list.
Since the Screens class is a convenience wrapper around AbstractOutput
objects that come from the Platform, it should not be platform-specific.
By dropping createScreens(), output-related code becomes simpler.
The default implementation of Screens::displaySize() returns the
bounding rectangle of all available outputs.
In case the Xrandr extension is unavailable, there will be a fake
output whose dimensions are the same as the dimensions of all screens
combined.
This is a typo that I forgot to fix, therefore not requesting code
review. After QVector::erase() has been called, we cannot use the
iterator as it will lead to undefined behavior.
Fix Rendering backend combobox that was not highlighted.
Particular case due to OpenGLIsUnsafe kcfg entry which is an indicating
flag and not a configurable setting.
Nothing here changes environ directly, and we're not interested
in passing a specific custom environment to kwin_wayland, so
don't use the (Linux-only) execvpe() for passing environment.
All find modules contain license information, which renders
COPYING-CMAKE-SCRIPTS redundant.
The reason why we have this file in the first place is purely
historical. Back in the kde-workspace repo days, not all find
modules contained the license under which they're distributed.
Right now when kwin exits, the user is taken directly back to the login
screen. The login session exits, so all processes then are killed by the
session.
This patchset introduces a mechanism to safely restart kwin. The socket
(typically wayland-0) remains alive and persistent across restarts. This
means if any process reconnects through it's own mechanism or a crash
restart handler the socket appears to work, and blocks until the new
kwin restarts.
This makes it secure and race free.
If the screen was locked at the time kwin went down, this is also
secure. Kwin now checks the status from logind at the time of launch, so
will immediately restore a locked state before any other rendering.
plasmashell provides the compositor buffers with an alpha channel and
without indicating the opaque region. Given that, kwin forces a bpp of
24 for desktop windows to improve performance. Unfortunately, there are
legit cases where plasma may attach a buffer that is not fully opaque,
for example when switching between activities.

This change introduces a new component - ColorManager that is
responsible for color management stuff.
At the moment, it's very naive. It is useful only for updating gamma
ramps. But in the future, it will be extended with more CMS-related
features.
The ColorManager depends on lcms2 library. This is an optional
dependency. If lcms2 is not installed, the color manager won't be built.
This also fixes the issue where colord and nightcolor overwrite each
other's gamma ramps. With this change, the ColorManager will resolve the
conflict between two.
We need the multimedia component only to play preview videos in a KCM.
The find_package(Qt5Multimedia) is not needed because we already check
if Qt5Multimedia QML module is present using ecm_find_qmlmodule().
The main motivation behind this change is to work around constant build
failures caused by buggy config file of the Qt5::Multimedia component.
Set -DLIBINPUT_HAS_TOTEM per file rather than per target so that all
targets that build it have the define.
This particular file is also used by some tests and this fixes the
warning that this ifdef resolves at once for all targets.
One of the annoying things about EGL headers is that they include
platform headers by default, e.g. on X11, it's Xlib.h, etc.
The problem with Xlib.h is that it uses the define compiler directive to
declare constants and those constants have very generic names, e.g.
'None', which typically conflict with enums, etc.
In order to work around bad things coming from Xlib.h, we include
fixx11.h file that contains some workarounds to redefine some Xlib's
types.
There's a flag or rather two flags (EGL_NO_PLATFORM_SPECIFIC_TYPES and
EGL_NO_X11) that are cross-vendor and they can be used to prevent EGL
headers from including platform specific headers, such as Xlib.h [1]
The benefit of setting those two flags is that you can simply include
EGL/egl.h or epoxy/egl.h and the world won't explode due to Xlib.h
MESA_EGL_NO_X11_HEADERS is set to support older versions of Mesa.

Effects are given the interval between two consecutive frames. The main
flaw of this approach is that if the Compositor transitions from the idle
state to "active" state, i.e. when there is something to repaint,
effects may see a very large interval between the last painted frame and
the current. In order to address this issue, the Scene invalidates the
timer that is used to measure time between consecutive frames before the
Compositor is about to become idle.
While this works perfectly fine with Xinerama-style rendering, with per
screen rendering, determining whether the compositor is about to idle is
rather a tedious task mostly because a single output can't be used for
the test.
Furthermore, since the Compositor schedules pointless repaints just to
ensure that it's idle, it might take several attempts to figure out
whether the scene timer must be invalidated if you use (true) per screen
rendering.
Ideally, all effects should use a timeline helper that is aware of the
underlying render loop and its timings. However, this option is off the
table because it will involve a lot of work to implement it.
Alternative and much simpler option is to pass the expected presentation
time to effects rather than time between consecutive frames. This means
that effects are responsible for determining how much animation timelines
have to be advanced. Typically, an effect would have to store the
presentation timestamp provided in either prePaint{Screen,Window} and
use it in the subsequent prePaint{Screen,Window} call to estimate the
amount of time passed between the next and the last frames.
Unfortunately, this is an API incompatible change. However, it shouldn't
take a lot of work to port third-party binary effects, which don't use the
AnimationEffect class, to the new API. On the bright side, we no longer
need to be concerned about the Compositor getting idle.
We do still try to determine whether the Compositor is about to idle,
primarily, because the OpenGL render backend swaps buffers on present,
but that will change with the ongoing compositing timing rework.
