Compositing today is ubiquitous. There is no reason to keep compositing
specific functions of Toplevel, Client and Workspace classes in the

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
https://devtalk.nvidia.com/default/topic/957814/linux/prime-and-prime-synchronization/),
perform any action causing a QtQuick window to be created by KWin, for
example, triggering the application switcher dialogue with alt + tab.
Ensure the desktop does not temporarily freeze.
Note, this required a Qt build that includes commit

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:
XWayland clients have a surface associated with them asynchronously. In this
case we don't directly want to set focus on this Toplevel, but wait until the
surface is set.

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.

Summary:
In the context of the Touch Screen and Screen Edges KCM, using the term "Run Command" to
refer to KWin is inaccurate and misleading. By using a string that starts with an action
verb and no ellipses, it is suggested that the action is literally to run some command,
prompting the user to think "which command will it run? How do I choose what it is?"
This patch changes the action text to "Show KRunner" which is the proposed new standard.
