Summary:
The Qt Wayland support for subsurfaces is broken in many ways, producing
graphical glitches and crashes:
https://bugreports.qt.io/browse/QTBUG-54888 for instance.
Using a QQuickWidget instead of a QQuickView avoids those issues, with
the additional benefit of a nicer API.
Test Plan:
Opened the KCM with kcmshell and systemsettings, no subsurfaces used
anymore.

Summary:
When one uses:
* breeze as of 5.12
* wobbly windows
* shaded window
* a distribution building with assert enabled
and starts to move a shaded window, KWin asserts. The root cause for
this is that WindowQuad::makeSubQuad has an assert for y1 being smaller
than y2. With the combination listed above this is not guaranteed. For
the left shadow quad the y1 and y2 are identical and thus trying to
split it, results in the assert condition.
The problem of the shadow quad having an invalid size might be addressed
as well with D10811. Due to that the generation of the quads is not
touched. Instead a sanity check is introduced to not try to split
already invalid sized quads.
BUG: 390953
FIXED-IN: 5.12.3

The detect functionality is still extremely bound to X11 and results in
a crash when clicked. Thus it's better to disable it completely in 5.12
on Wayland.

Summary:
If the cursor theme failed to create KWin crashed due to an endless
recursion. There are two reasons for this fault:
1) When the physical size does not exist we perform a division by 0
which results in an invalid size going into wl_cursor_theme_load
2) We emit the signal that the cursor theme changed even if it didn't
change thus creating an endless recursion
This change addresses both problems: it checks that the size is not 0
and changes the handling for theme update to only destroy the previous
theme if the new theme could be created and only emits the signal if
things change.

Summary:
On touch down a first hover motion is sent to the decoration. Thus e.g. a
button enters the hovered state. On touch release so far the decoration
did not get a leave event resulting in the button still being hovered.
This change ensures the leave event is sent or if the pointer is also on
the decoration a motion to the pointer position is sent.

Summary:
If the window never provides the appId, we would not get an icon for
the window. This happens for example for KWin's internal windows which
don't set the app id as KWin also doesn't have a desktop file. With this
change the DebugConsole has a window icon in the decoration.
Test Plan: Extended tests and manual verification of DebugConsole

Summary:
The window rule detection is too bound to X11 for it to work for
Wayland windows. In fact it results in the config module just crashing.
Thus it's better to just disable the items in the menu. As it's only for
X11 windows we can also enforce platform xcb for the rules dialog.
Test Plan: Menu disabled on Wayland window, menu enabled on Xwayland window

When a window was being moved the touch handling performed the wrong

did not enter the correct code paths, thus quick tiling was for example
not functional.

Summary:
KDecoration has two new pure virtual methods. Due to that one cannot
build KWin in the stable branch. This makes bug fixing rather cumbersome
as one also needs to switch the kdecoration branch.
This rather unusual change for a stable branch improves the
compatibility by adding the new virtual methods without doing anything
and without marking them as override, so that the code can compile with
a kdecoration from 5.12 and a kdecoration from master.
Test Plan: 5.12 branch compiles with kdecoration master branch

Summary:
The support for interactive point selection was missing. This results in
the ColorPicker dbus API always returning an error on X11. We either need
to disable the ColorPicker on X11 or add support for this functionality.
As the X11 platform basically supports selecting a point in the
interactive window selection it makes more sense to add this missing
method in the platform than to disable support of color picker effect.

Summary:
We send out too many configure requests when finishing move resize which
also triggers quick tiling. This change addresses the problem of the too
many configure requests by making the configure method check whether
geometry updates are blocked. And to make this work properly for the end
of finish move resize the complete method is wrapped in a geometry
update blocker.
BUG: 388072
FIXED-IN: 5.12.1
Test Plan:
Quick tiling test passes, both Wayland and X11 windows are
quick tiled correctly.

Summary:
While investigating BUG 387313 I noticed that blending might be disabled
for subsurfaces. Blending was disabled before rendering the subsurfaces
and it is not checked whether the surfaces have an alpha channel or not.
This change addresses this problem by disabling blending after all
subsurfaces have been rendered and enabling blending if a subsurface has
an alpha channel.
Unfortunately this does not fix the investigated bug.

Summary:
With GTK applications our code showed issues. With GTK the sequence for
a menu or dialog window is:
1. create surface
2. create server side decoration
3. request csd
4. create xdg_shell_surface
Which result in KWin to have the ServerSideDecoration object being
created before the ShellClient is created. The connect for mode changed
happens in ShellClient, which is too late to catch that the window
requested client side decoration. Thus KWin created a decoration about
things such as a menu.
This change moves the acknowledge of the mode to WaylandServer. As we
anyway always acknowledge the requested mode we can also do it there and
don't require ShellClient to be present. Thus when the ShellClient is
created the mode is properly reflected and no decoration is created.

22% of cpu time in the method hasTransientInternal is spent doing
a cast to Client *, while at the begining of the method, the cast to

Once again KActivities causes a delay in the startup of KWin. This is
not the first time it happens, that has been a problem since the start
of the Wayland project.
In the past we added a compile time switch due to that and added a
runtime switch once it stoped freezing (20a9a2a247).
And now it broke again, so let's disable again.
KActivities doesn't make sense on Wayland anyway as there is no activity
support for Wayland windows. Once KActivities is able to be used without
freezing KWin on startup and being able to ensure that it won't break
again we can reenable. But I expect guarantees about that. This must be
ensured by proper autotest support to verify that in future usage of
KActivities in the display manager doesn't freeze it.
This is maintainer decision, due to that no pre-commit review.
