Summary:
When clicking the maximize button without moving the mouse, the maximize
button stayed in hover state till the mouse moved. The reason for this
is that the PointerInputRedirection does not perform an update on the
geometry change of a window.

Summary:
In 47343fb we made GBM buffer shared.
What we wanted to do was:
Unbox the shared_pointer<GBMSurface> to give us a GBMSurface* object
Call the gbm_surface*() on that operator
Then cast that to a void* for eglCreatePlatformWindowSurfaceEXT
What we did:
Cast the std::shared_ptr<GBMSurface> to a gbm_surface* then cast that
to void*.
This is just a garbage value and it crashes in Mesa when we do our first
paint.
I've replaced that with an explicit method then we can use shared_ptr's
-> operator rather than get() which does the right thing in a readable
way.
Test Plan:
It crashed after rebasing to master (for Aleix too)
No longer crashes

Summary:
The gbm_surface is owned by the EglGbmBackend, but it's not the only one
using it. The DrmSurfaceBuffer is also using it and needs it to destroy
the gbm_bo. Now this can become a problem in the following situation:
* a page flip is still pending
* the EglGbmBackend destroys the gbm_surface
-> when the page flip happens the DrmSurfaceBuffer will try to destroy
the gbm_bo and crash as the gbm_surface is no longer valid. This
situation can happen when switching screens or when switching compositing
backend (OpenGL 2 -> OpenGL 3).
To address this problem a class GbmSurface is added which wrapps the
gbm_surface pointer. The EglGbmBackend creates and holds a shared pointer
to the GbmSurface and passes that one to the DrmSurfaceBuffer. So when
cleaning up the gbm_surface only the shared pointer is reset and in case
the DrmSurfaceBuffer still needs it, it can access it without problems.

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.

So far the method only operated on X11 clients. So when the last desktop

Summary:
Instead of calling reconfigure() on screen size changes, which deletes
and recreates the effect, we can just update the one texture that's mapped to
the screen size.
---
From the wayland commit.
>What surprises me is that BlurManager recreates for Output changes.
>That sounds like a bug in KWin (or an area which could be improved).
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.

Summary:
Similar to the Blur patch. Arguably rven less reason as this doesn't
have a texture the size of the workspace.
We don't need to delete and recreate the entire effect every time the
screen changes; This deletes the wayland global which causes quite a bit
of extra work for the clients.

Changed resolution under X, and scale under wayland
Panel looked the same and nothing exploded

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:
It was possible that we performed an early exit when the caption changes
and this results in the visible name being wrong. E.g if we have two
windows called foo, the second one has the visible name "foo <2>". After
changing that to "bar" the bug resulted in it still being the foo
variant instead of getting cleared.

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

Summary:
The RuleBook is created during Workspace startup, so it's a required

X11 is available.

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:
TabBox implemented a custom way to check whether two windows belong to
the same application. KWin internally has API for that which does it
better, in a standardized way and even across windowing system.

on X11 and starts to work on Wayland.

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.
