Summary:
The compositor tries to switch to the next tabbox client when currently
highlighted client is closed. Though there is a small issue with that.
Because the switch happens too late, a dangling pointer can be inserted
into the unconstrained stacking order, which can lead to a crash later on.
There are two cases:
- compositing is on;
- compositing is off.
Compositing is on: TabBox will try to un-elevate currently highlighted
client, though by that time the client no longer owns EffectWindow, so
this is basically a no-op (that's why we haven't experienced this bug
before).
Compositing is off: TabBox will try to restack currently hightlighted
client under the next tabbox client. Given that the restack method
doesn't do any sanity checks(see Client::manage why), a client that is
about to be destroyed will be re-inserted back into the unconstrained
stacking order.
This change ensures that the switch happens before currently highlighted
client is removed from the stacking order.
BUG: 406784
Test Plan:
- Turn off compositing;
- Follow steps to reproduce in the bug report (see comment 2).

KWin replaces any non-printable character with a space. This check does not
handle surrogate pairs correctly. Additionally, translators sometimes insert
non-printable soft-hyphens into titles, which also cause KWin to display a
space instead.
This code adds the missing surrogate handling, and (to fix both issues), also
removes non-printable characters instead of replacing them with a space.
Also moved the changed test after these changes, so that changes in non-
printable characters do not cause unneeded redraws.
Unit tests adapted by Vlad Zagorodniy.

kwrite /tmp/Test😣.txt shows correct title. I also tested actual non-printable

Summary:
Instead of seeing the cursor <--> on the left edge you now see an icon
that looks like |<- .
This brings kwin decorations in line with GTK CSD icons.
In theory this is also useful to tell which window will resize in the
case of side-by-side windows (regardless of whether borders are on or
not). In practice with the adwaita icon theme I tested with it's not
very intuitive to realise which is which till you learn the icon.
Change is more involved than it should be as Qt::CursorShape doesn't
have these entries, and I don't want to shadow that enum internally or
have
to change kwin effect code.
Specifics depend on cursor icon theme if they are not present it will
fallback to the <--> icon. (Breeze does not have them currently)

Resized some windows (on X and on Wayland)
Correct icon appeared on Adwaita
Existing icon appeared on Breeze

Summary:
Commit 5d9027b110 introduced a regression in TabBox by using the generic
framework inside KWin to test for same application. What I did not
consider was that the code in TabBox was "broken by design". It didn't
use the generic check as that is too strict and considers windows from
different processes as not belonging to the same application. But this
is not wanted in the case of TabBox.
On the other hand the change itself is an improvement to also support
Wayland in a better way and not have special handling situations. Thus
just reverting would not help.
Instead this change addresses the problem by extending the internal API
and to allow more adjustements. So far there was already an
"active_hack" boolean flag. This is extended to proper flags with an
additional flag to allow cross application checks.
The checks in Client which would filter out different applications check
for this flag and are skipped if set. In addition ShellClient also adds
support for this flag and compares for the desktop file name.
Thus we get in TabBox the same behavior as before with the advantage of
having a better shared code base working on both X11 and Wayland.

Summary:
On Wayland we have the sync disabled as it doesn't work properly. This
allows us to also move the sync event handling into the X11 standalone
platform.
The code is slightly refactored: instead of passing the event to each
Client, we search for the matching Client. For that the SyncAlaram struct
is added to public section of Client. The method to handle the sync
doesn't need the event any more and is moved from events.cpp to
client.cpp.

Run Xephyr+kwin_x11, resized a window and verified through
gdb breakpoint that the sync still works

Summary:
Bringing another caption feature from X11 to Wayland. If we have
multiple windows with the same caption, starting from the second window
a suffix <number> is added.
E.g. if we have three windows with caption "foo", the naming is:
* foo
* foo <2>
* foo <3>
The change tries to use as much shared code between the X11 and Wayland
implementation. Unfortunately it's not possible to share completely as
the X11 implementation does X11 specific things like editing the visible
name.
By sharing the code the numbering also works cross windowing system.
That is if a window is called "foo" on X11, a new window on Wayland with
caption "foo" will get adjusted to "foo <2>" and vice versa.
The change also eliminates a duplicated signal for captionChanged in
ShellClient (found by test case).
By using the shared implementation on X11 side a bug gets fixed which
got introduced with the support of "unresponsive", this is no longer
considered and the numbering still works even if there is a window which
is unresponsive.

I don't know what the idea of entering QWhatsThis mode was, but the code
is pretty much dead. There is no QWhatsThis window shown as KWin does
not have any UI or help. The window which eventually gets shown in
context help is provided by the client application.
Furthermore KWin never leaves the QWhatsThis mode. At least one code
path entering in leave is dead in general and one at least on Wayland
(but probably also on X11 as the window never gets shown).
The show context help functionality works fine without the QWhatsThis
handling, so let's remove it.
I tried to blame what was the idea behind it, but it was unchanged since
decades and blame ended in a code moving commit.

This is what 7ce380497f tried to do (and got reverted by my previous commit).
The approach is basically the same, just temporarily fake that the window
is on all activities, thus it will be temporarily shown for the session
interact, but this time there seem to be no broken side-effects (and if there
are, they'll be at least limited to activities and not break virtual desktops).
Also, 'needsSessionInteract' was a misnomer - it certainly wasn't set for all
windows that needed session interaction. Just call it what it really is.
Differential Revision: https://phabricator.kde.org/D5614
The member variable is not what determines which desktop a window is on,
it's more like caching the state. Therefore trying to fake a new value
eventually leads to inconsistencies, e.g. having KWrite open with unsaved
changes on inactive desktop results in the window ending up on all desktops
after session save (both successful and cancelled).
This pretty much reverts the whole 7ce380497f that introduced this and also
a0a976885c that tried to fix some of the problems resulting from it.
The original problem of session saving of windows of inactive activities still
remains, to be fixed by another commit.

Summary:
So far KWin used the window title provided from the window directly
without any sanitizing. This could result in broken window decorations
if the title included line breaks. Those were passed to the decoration
and depending on the way how the decoration renders the title, it could
result in visual breakage.
Having line breaks in a window title doesn't make sense. Given that KWin
now simplifies the title when copying it to it's own structure. This
also ensures that the title passed to e.g. task manager does not have
any line breaks on Wayland.

Summary:
KWindowSystem provides a KDE specific property for the desktop file
name. This allows KWin to take the icon from the desktop file. The
advantage from the desktop file is that KWin normally gets higher
resolution icons than provided through the xproperty based icons used
previously. If the desktop file does not provide an icon name, KWin
falls back to the previous implementation.
As on Wayland the icon is taken from the desktop file name already the
code for X11 and Wayland is merged in AbstractClient. Also to the
PlasmaWindowInterface the appId is taken from the new desktop file
instead of the resourceName. Due to that for Xwayland windows where KWin
knows the desktop file name it can be passed to PlasmaWindowInterface.
This allows e.g. the task manager to better map the windows to
applications and provide better icons. Also it means that icons do not
need to be passed as bitmap data to the clients.
Test Plan:
Verified that icon is taking from desktop file if provided and
from X property if not provided and that Wayland windows still have icon.

Client::updateInputWindow operates with the decoration size. The method
gets called from various points when changing the window geometry. If at
that moment the decoration has not updated yet, the borders might be at
a wrong position.
This behavior could be triggered when a window requested to change the
state to maximized. During maximization the decoration still had the
wrong size when updateInputWindow was called, thus an interactive area
inside the window was created.
To circumvent this problem updateInputWindow is now also called whenever
the window decoration changes.
As a note: that a maximized window has resize only borders is wrong. Kwin
should be protected against that.

unredirect fullscreen option was shown.

Summary:
Rational: unredirect fullscreen windows is a weird beast. It's intended
to make fullscreen windows "faster" by not compositing that screen. But
that doesn't really work as KWin jumps out of that condition pretty
quickly. E.g. whenever a tooltip window is shown. KWin itself has a
better functionality by supporting to block compositing completely.
The complete code was full of hacks around it to try to ensure that
things don't break.
Overall unredirect fullscreen has always been the odd one. We had it
because a compositor needs to have it, but it never got truly integrated.
E.g. effects don't interact with it properly so that some things randomly
work, others don't. Will it trigger the screenedge, probably yes, but
will it show the highlight: properly no.
By removing the functionality we finally acknowledge that this mode is
not maintained and has not been maintained for years and that we do not
intend to support it better in future. Over the years we tried to make
it more and more hidden: it's disabled for Intel GPUs, because it used
to crash KWin. It's marked as an "expert" option, etc.
It's clearly something we tried to hide from the user that it exists.
For Wayland the whole unredirect infrastructure doesn't make sense
either. There is no such thing as "unredirecting". We might make use
of passing buffers directly to the underlying stack, but that will be
done automatically when we know it can be done, not by some magic is
this a window of specific size.
Test Plan:
Compiles, cannot really test as I am an Intel user who never
had that working.

This change ensures that the window gets destroyed before the xcb
connection gets destroyed.

The damage event of the Surface does not consider the offset through
the server side decoration. Due to that we need to have a different
repaint and damage area. As Toplevel::addDamage(QRegion) is only used
in the Wayland case the repaint adjustment is removed from the generic
implementation and moved into the specific implementations. While it
wouldn't hurt to have the repaint adjustment in Toplevel, it would
trigger a repaint of an unchanged area.
For Client I'm not sure whether it's correct without considering the
clientPos. My testing shows it's working, but that might also just be
do to Xwayland using OpenGL buffers. Needs further testing.
The only clients that really seem to rely on it are
Java and they're apparently "broken", resp. extremely
picky on the tiemstamp and probably happily refuse focus
if it's *not* equal to the current server time (ie. anything else
happens at this moment) and overmore feel oblieged to act as WM
