With the new Wayland only mode we start too fast and it can happen that
the initWithWorkspace is called before the client connection is fully
setup. This would result in a crash in the idletime plugin once it tries
to create a seat.
To prevent this problem the code is split out into a dedicated method
and only invoked if all interfaces have been announced on the internal
connection.
BUG: 385397
FIXED-IN: 5.11.1
guix (like nix) used a separate prefix for each package. Thus the header
files for
qtdeclarative are in /gnu/store/…-qtdeclarative-5.9.1/include/qt5/ while
the ones for
qtbase are in /gnu/store/…-base-5.9.1/include/qt5/. This means that
*each* dependency's include directory must be specified. This is in
contrast to a "normal" Unix-system, where all includes end up in
/usr/include/qt5 and missing to defined some include-dependencies does
often not raise an error.

>What surprises me is that BlurManager recreates for Output changes.

I had thought the same and wrote this (though wanted to have kwayland fixed first)
Test Plan:
Logged in and out (my screen resizes on startup due to scaling)
Tested on my X machine by turning a screen off. Nothing broke, plasma
panels looked the same.
Note: Eike tried this patch last week and claimed kwin still crashed.
We don't have a backtrace so it could have been something unrelated,
applied wrong or that he was deliberately lying to wind me up.

We don't need to delete and recreate the entire effect every time the

of extra work for the clients.

Summary:
Creating the X11Filter directly on startup caused a regression as the
filter got too early in the chain and stole events from the
XInputIntegrationFilter. We don't need the filter all the time, but only
when we have established the TabBox grab. Likewise we can destroy the
filter again when releasing the TabBox grab. So it's much more
encapsulated now.

Summary:
Several effects announce a support property atom on the root window. This
change forwards the KWin::Application's signal that the xcbConnection
changed to the EffectsHandler so that the effects can respond to it.
All effects which announce a support property connect to this new signal
and re-announce the property. In case the xcb connection died (future
XWayland crashing case) it is set to XCB_ATOM_NONE by that. In case the
xcb connection got created (future delayed XWayland startup) the atom is
set to the proper value.
In addition all usages of the support properties are guarded, so that no
nonesense actions are performed if the support property is XCB_ATOM_NONE.

Summary:
The code in events.cpp was problematic as it was called in a Wayland
session. So KWin changed outputs, this gets mirrored to XWayland and
then KWin reacted on the XRandR event and might have even changed the
refresh rate due to that - bad idea.
This change moves the code into the already existing X11EventFilter for
XRandR events in XRandRScreens.

Summary:
We had a few places (e.g. DebugConsole, Platform) where the Scene was
cased into a SceneOpenGL to access the backend and get the extensions.
This change simplifies that by adding a virtual method to Scene directly
which is implemented in SceneOpenGL and returns the backend's
extensions.
Thus the casts to SceneOpenGL are no longer required.

Opened debug console to verify extensions are listed,
triggered Outline to verify the sharing QPA context gets created.

Summary:
Several of the subclasses are already derived from QObject.
The main reason is that the class should be moved out of KWin core in
order to move the OpenGL scene into a plugin. As Compositor calls into
the AbstractEglBackend to unbind the wayland display this creates a
problem which is easily solved by turning the AbstractEglBackend into a
QObject and connect to the signal emitted by the Compositor.

Summary:
So far the Platform performed a deep query into the AbstractEglBackend
to get information such as EGLContext, EGLConfig, EGLSurface. This
change adjusts this so that the AbstractEGLPlatform forwards it directly
whenever it gets informed about one following the approach already used
for EGLDisplay. This simplifies the code a lot and allows to remove the
dependency on the actual scene backend from the Platform (in order to
split out the SceneOpenGL into a plugin).
Test Plan:
Run nested kwin_wayland, triggered Outline which requires all
those methods.

Summary:
The syncing of the window geometry to the internal geometry can
unfortunately cause a freeze in very special conditions:
1. create QML component
2. a Plasma::Dialog gets created
3. It creates the DialogShadows
4. This triggers QGlobalStatic creation which locks a non-recursive
mutex
5. The creation of DialogShadows creates a Registry and triggers a
roundtrip on the Wayland server
6. KWin processes all Wayland events
7. This triggers the creation of a ShellClient
8. The ShellClient has a PlasmaShellSurface which requested a position
9. The new geometry does not match the geometry of the Plasma::Dialog
10. ShellClient syncs the geometry to the Plasma::Dialog
11. Plasma::Dialog updates the theme because window geometry changed
12. This accesses the DialogShadows...
which is still in the non recursive mutex and we have a freeze.
By delaying the sync to the end of cycle we jump out of this deadly
sequence.
BUG: 384441
Test Plan:
The freeze doesn't hit any more. It's possible that some test
cases need adjustments.

Actually they could go directly as nothing in KWin uses them anymore.
But there are more functions in kwinglobal which need to go as they
don't support restarting XWayland. So instead of breaking internal ABI
several times, just deprecate till everything is prepared.
Was missing a return and due to that the decoration renderer never
got added to the Decoration.
Thanks to code coverage reports on build.kde.org! They showed me that
something must have went wrong with the commit series.
Summary:
The SyncManager is highly X11 dependent and doesn't make much sense on
Wayland. It should already be guarded by the check for
GL_EXT_x11_sync_object, but better be safe than sorry, so explicit check
for on X11.

Summary:
The compositor needs to claim the X11 compositor selection and redirect
the X11 windows. This of course only makes sense when having X11 support.
This change refactors the code so that if X11 support is missing the code
is not executed, but as soon as X11 support comes available the selection
gets claimed.
Also if the connection goes away the selection is deleted, though it
might be that this does not work as KSelectionOwner might call into xcb
and cause a crash. This needs to be tested once we start supporting
XWayland going away.

This change is similar to D7232 and moves the scene_qpainter into a
dedicated plugin. Compared to the XRender case it's more complicated as
the platform plugins need to implement a platform specific backend.
The base implementation for this part used to be in scene_qpainter. As
the idea is to completly move it away from KWin core it would be point
less to still have the backend definition in KWin core, but it cannot
be in the scene plugin as otherwise all platforms need to link the
plugin.
To solve this a new platformsupport subdirectory is added which contains
the scene platform backend as a static library. For the OpenGL scene such
a static library will also be required.

Needed by testing of QPainter scene to access the back buffer. Exposed
as a virtual method in Scene, so that the test does not have to cast to
SceneQPainter.
Summary:
First step for loading the compositor Scenes through plugins. The general
idea is that we currently needlessly pull in all the Scenes although only
one will be used.
E.g. on X11 we pull in QPainter, although they are not compatible. On
Wayland we pull in XRender although they are not compatible.
Furthermore our current Scene creation strategy is not really fault
tolerant and can create situations where we don't get a compositor. E.g
on fbdev backend the default settings won't work as it does not support
OpenGL.
Long term I want to tackle those conceptional problems together:
we try to load all plugins supported by the current platform till we have
a scene which works. Thus on Wayland we don't end up in a situation where
we don't have a working compositor because the configuration is bad.
To make this possible the switch statement in the Scene needs to go and
needs to be replaced by a for loop iterating over all the available
scenes on the platform. If we go there it makes sense to replace it
directly with a plugin based approach.
So this is a change which tackles the problem by first introducing the
plugin loading. The xrender based scene (as it's the most simple one)
is moved into a plugin. It is first tried to find a scene plugin and only
if there is none the existing code is used.
