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.

We need this to use the new OnScreenNotification in the screenshot

Summary:
The OnScreenNotification gets moved during its placement. This update
of the geometry did not get synced to the QWindow's geometry as it
should.
The reason for this is the rather special implementation of
AbstractClient::move. This just modifies the geom variable and does not
call into setGeometry at all. Instead a virtual doMove method is invoked
to inform the platform specific client implementation about the move of
the window. For a "normal" ShellClient that is fine - there is nothing
to do.
This change adds an implementation of doMove in ShellClient to sync the
geometry to the internal window. This is not yet enough to fix the
geometry of the OnScreenNotification. It gets placed with a
GeometryUpdatesBlocker in place causing the doMove never to be called.
Instead setGeometry is invoked again when the geometry updates get
unblocked. So far ShellClient did not do anything in this case. This
change ensures that at least the doSetGeometry method is performed again.
Test Plan: Added test case and manual testing of OnScreenNotification

Summary:
This change adds support for opacity on a KWin internal QWindow.
Calling QWindow::setOpacity syncs the value to the ShellClient
representation of the QWindow.
This is needed for fading out the OnScreenNotification on mouse
over.
Test Plan: Added auto test and manual test

Summary:
This is a preparation step for no longer creating a socket in the tests
and slightly simplifies the init test code.

Summary:
In order to add more tabs which can further help monitoring how KWin
handles some aspects the DebugConsole is changed to not take keyboard
input. This means it can only be navigated using pointer device or touch
screen.
This is needed for adding a new tab to monitor clipboard changes. On
Wayland sometimes windows don't get the clipboard, so it would be
helpful to have a debug monitor to see when the clipboard changes. But
for that debug console window may not take keyboard events.
To support this DebugConsole sets the WA_ShowWithoutActivating attribute
which gets honored by the InternalWindowEventFilter and does not forward
key events to such windows.

Summary:
KWin always has a few internal windows around which are not visible.
A QWindow created somewhere, but not shown. Such windows should not
be part of the stacking order.
If they are it breaks code which looks at the top most window in the
stacking order like e.g. SlidebackEffect.
This change ensures that the stacking order gets updated whenever a
ShellClient gets hidden and that internal windows with isShown being
false are excluded from the stacking order.

This allows finding the Toplevel for a QWindow which is on Wayland a
ShellClient and on X11 an Unmanaged. This can be used to simplify
code when a Toplevel is needed for an internal QWindow without having
to do platform specific checks.
Creating a dedicated method for the leave event on client.
This restructuring of the test should hopefully work around the
failing test condition on build.kde.org.
Summary:
So far when KWin intercepted a key event a leave was not sent to the
Wayland surface currently having keyboard focus. This could result in
the Wayland application to start repeating keys. E.g.
1. application gets key press event
2. This triggers an internal window to show
3. key release goes to KWin internal window
4. application starts to repeat key as there is no release
With this change whenever KWin intercepts the key event e.g. due to
* internal window
* Effects grabbing key event
* Tabbox
the focused keyboard surface is set to null, thus triggering a leave
event and the client not starting to repeat the event.

Summary:
With this change KWin can create window decorations for internal windows.
Thus it's also possible to move internal windows and resize them which is
especially important for the debug console.

Summary:
If KWin fails to start the Wayland server due to XDG_RUNTIME_DIR not
being set, kwin_wayland should terminate with an error condition but
not crash.
This change makes sure that KWin detects that the Wayland server does
not work and terminates the startup early and ensures that it doesn't
crash while going down.
An error message is shown that we could not create the Wayland server.
Test Plan:
Test case added which verifies that WaylandServer fails to
init. Manual testing that kwin_wayland exits with error 1.
