Summary:
A keysym can be assigned to several keycodes, so more proper way to
determine whether given modifier is depressed is to iterate over all
returned keycodes and see if any is pressed.
If we check only the first keycode, then alternative mappings may not
work, e.g. alt key mapped to win, etc.

Summary:
Unfortunately Aurorae decoration engine creates several internal clients
per each decoration. One of those clients represents QOffscreenSurface,
which is not a toplevel. Given that no QWindow object will be found for
such clients, m_internalWindowFlags contains undefined value.
Luckily, QOffscreenSurface sets FramelessWindowHint flag, but because
InternalClient is not able to find matching QWindow object, cached
QWindow flags won't have that hint set.
Thus InternalClient will attempt to decorate QOffscreenSurface. A new
Aurorae decoration will be created, which means a new QOffscreenSurface
will be created, which means a new Aurorae decoration will be created,
and so on.
This change restricts subset of internal clients that can be decorated.
Only clients with valid m_internalWindow can be decorated. If m_internalWindow
isn't null, then m_internalWindowFlags is guaranteed to be valid as well.

Summary:
The internal window test is failing on CI because the client add spy waits
are not triggered. The signal has been emitted already at this point.
Removing them fixes this (the condition is still checked by subsequent
count verify on the spy) in all but one instance. In this case the wait
needs to be guarded.
Is there a more general approach to it? Always guarding is ugly. Also when
was this test regression introduced? In the past we must have had some
slack until the signal was fired to start the wait call.
Test Plan: Internal window test passes with this patch again.

The screenlock fails on X11 if it can't grab the keyboard.
We can't nicely solve the generic case. We can solve the common case of
a kwin effect being active.
It's not critical, arguably not even desirable to have these effects
persist after the screen is locked through an external trigger. We can
just close the effect early.
Key grabs have to be relased early before the close animation completes
so that the locker doesn't have a race based on animation times.
It's not ideal, but no worse than the current state for not much work.

Summary:
Plasma's Task manager exposes an optional feature whereby the user
can middle-click on a window to close it, but the Present Windows effect
does not do the same.
The presence of a close button you can left-click does not replace the desirable
feature to be able to middle-click on a window to close it, because then the
whole window becomes a click target, so it can be much much faster than
having to aim for the little close button. Also it's off by default, so a user
who goes out of their way to turn it on is signaling that they want to accept the
risk of accidentally closing a window by accident.
Finally, the feature is not allowed for left-click, so people can never accidentally
wreck Present Windows for themselves by assigning it to left-click by accident
and then mistakenly closing their windows.
This reverts commit 55585514f9.

Summary:
QtQuick windows created by KWin currently use the default swap interval
of 1, meaning buffer swaps will block until vblank. However, this
results in a problematic interaction on hybrid graphics systems running
the proprietary NVIDIA driver. VSync on such setups relies on a system
called "PRIME synchronization", where the xf86-video-modesetting driver
controlling the display will signal the NVIDIA driver when vblank has
occurred. The issue is that it will only do so if there has been damage
to the screen.
So, when KWin creates a QtQuick window, compositing will stop waiting on
the window to render, therefore no damage to the screen will occur. But
this means that no vblank notifications will be delivered to the NVIDIA
driver, so the glXSwapBuffers call by the QtQuick window will block
perpetually. The end result is a freeze of the desktop.
To get around this, we can simply disable vsync for QtQuick windows by
setting the swap interval for the default QSurfaceFormat to 0. Since
they are redirected, this shouldn't cause any tearing.
BUG: 406180
FIXED-IN: 5.16.2
Test Plan:
Using the proprietary NVIDIA driver on a hybrid graphics system, with
PRIME synchronization enabled (see

example, triggering the application switcher dialogue with alt + tab.

Summary:
There are several issues with code of AbstractOutput class:
(a) Some methods are documented, and some are not. In general, we tend
to document all public methods in KWin core. It looks like a very
minor issue, but there are methods that have very ambiguous return
value. One such method is geometry(). It's not obvious whether the
returned geometry is in device independent pixels or not;
(b) There's a mix of methods defined in the cpp file and in the header.
This is not very good because reading such code becomes a bit harder
if you don't use any fancy IDE;
(c) Missing Q_DISABLE_COPY, etc.
This change addresses these issues, so the code is a bit more readable
and easier to work with.

Since d51b8dc093 the test fails on CI, apparently because we test with
Breeze default settings, which is no borders now and we can move a bit into
the window geometry and still be on the border if borders exist, otherwise
not.
For now fix it by checking if there are borders or not and then test
accordingly. But long-term we should test both cases and besides not rely on
external decorations for our test, instead use a fake specific for our
integration testing.

Summary:
This is an alternative solution to T8707 and in comparision to D13276 a less
drastic change to KWin's default behavior.
Instead of changing the border size default for all KDecoration plugins by
switching the default from border size Normal to None introduce new
functionality, which allows a KDecoration plugin to recommend a border size in
its metadata. By default KWin listens for these recommendations and sets the
border size accordingly.
If there is no metadata recommending a border size, KWin falls back to the
current setting of Normal sized borders.
A user is able to override the recommendations from the KCM, which has been
extended accordingly.
Test Plan: Manually with adjusted metadata of Breeze.
