Summary:
In order to pick the next client to activate we traverse the stacking
order from bottom to top and assign to each client a score. The client
with the best score will be activated next. Function that assigns score
bases its decisions purely on geometry. This may backfire if there are
couple maximized or fullscreen clients on the screen - we'll activate
the bottom-most client.
This change toggles direction we traverse the stacking order. If there
are several clients with an identical score, then prefer the top-most
client, the one that the user most likely sees at the moment.

Summary:
When ShellClient tears down, it needs to access RuleBook in order to
discard temporary rules. The problem is that WaylandServer outlives
Workspace and therefore so does ShellClient.
We can't guard against the case when RuleBook::self() is nullptr as it
is vital to discard temporary rules.
This change adjusts termination sequence so all shell clients are
destroyed before Workspace(and thus RuleBook) is gone.

Doxygen comments with this style look balanced and neat, but many people
that contribute to KWin don't follow this style. Instead, they prefer

Reviewing such changes has been a bit frustrating for me (so selfish!)

This change switches doxygen comment style in KWin to a more traditional

Summary:
Currently code base of kwin can be viewed as two pieces. One is very
ancient, and the other one is more modern, which uses new C++ features.
The main problem with the ancient code is that it was written before
C++11 era. So, no override or final keywords, lambdas, etc.
Quite recently, KDE compiler settings were changed to show a warning if
a virtual method has missing override keyword. As you might have already
guessed, this fired back at us because of that ancient code. We had
about 500 new compiler warnings.
A "solution" was proposed to that problem - disable -Wno-suggest-override
and the other similar warning for clang. It's hard to call a solution
because those warnings are disabled not only for the old code, but also
for new. This is not what we want!
The main argument for not actually fixing the problem was that git
history will be screwed as well because of human factor. While good git
history is a very important thing, we should not go crazy about it and
block every change that somehow alters git history. git blame allows to
specify starting revision for a reason.
The other argument (human factor) can be easily solved by using tools
such as clang-tidy. clang-tidy is a clang-based linter for C++. It can
be used for various things, e.g. fixing coding style(e.g. add missing
braces to if statements, readability-braces-around-statements check),
or in our case add missing override keywords.
Test Plan: Compiles.

Summary:
Currently, the Night Color manager supports three operation modes:
* Automatic: in this mode, screen color temperature is computed based on
the current position of the Sun. In order to calculate sunrise & sunset
times, the manager needs coordinates of the user, which are provided by
Plasma;
* Location: this mode is very similar to the Automatic, except one minor
detail: user needs to provide his/her/their location. This mode can be
very useful if coordinates provided by Plasma are incorrect;
* Timings: unfortunately we can't compute timings of the Sun for people
living near Earth poles. This mode allows the user to specify timings of
sunrise and sunset as well the transition time.
This change introduces another mode, called Constant. With this mode the
screen color temperature is constant throughout the day. The new mode
can be useful for people wishing constant screen color temperature or
just for people living near Earth's North or South poles.

Is there a more general approach to it? Always guarding is ugly. Also when

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:
The size passed to an XDG shell configure request should match the
window size of the given window, we don't want to include the size of
any shadows that may be drawn by the client.
Kwin has the same concept of geometry for both window management, input
and rendering.
In order to approach this in a way that does not risk any regressions
with kwin's current structure AbstractClient::geometry remains the
canonical source and we handle the window within that internally within
ShellClient treating the windowGeometry as a set of margins from this.
This is part of a much bigger task (T10867). This patch addresses
windows growing when starting a drag based resize.

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-

window rules. Most notably the maximised placement strategy used on

By blocking sending configure events we will have flushed the correct
initial state before sending a single atomic correct event to the
client. It also adds a hook to re-evaluate rules now that all properties

Arguably this applies to WlShellSurface too, but I've left it unchanged

This patch moves the code back into main_wayland and removes the

There was also a misnaming of methods.
Previously:
continueStartupWithScreens was called after platform screens are created
continueStartupWithScene was called after the scene was created
continueStartupWithXwayland was called before xwayland is created
This was confusing, so the names have been shuffled around to follow a
consistent pattern of what has been done so far.

Summary:
On Wayland we cannot switch from OpenGL to QPainter compositor as this
would break any running OpenGL application. KWin registers it's
EGLDisplay to Wayland and without OpenGL this doesn't make sense any
more. We are not able to render OpenGL buffers in the QPainter
compositor.
While it's theoretically possible to switch from QPainter to OpenGL it
doesn't make any sense for the same reason. Any running OpenGL
application would be using llvmpipe and could not be switched to proper
OpenGL.
This change stores the selected compositing type in Platform and the
implementations can use it to restrict the supported compositors. On X11
we don't need this, all other Platforms implement the restriction. Thus
it's no longer possible to switch the backends at runtime.

Adjusted tests run, no runtime test as gui doesn't support
switching to QPainter anyway.

Summary:
Most of the functionality which is special to internal clients is moved
from ShellClient to InternalClient. As KWin's qpa is still bound to the
Wayland protocol InternalClient inherits from ShellClient. Due to that
some aspects in ShellClient are "weird". ShellClient still detects
whether it's an internal client and uses the variable m_internal to
capture the state. This is required as we cannot use the isInternal
method. Most of m_internal usage is in init which is called from
constructor of ShellClient. Thus it's not possible to call into virtual
methods of InternalClient.
Also some of the code is duplicated and some methods are temporarily
marked as virtual.
The next step will be to remove ShmBuffer for internal windows which
should decouple the two implementations further with the long term goal
of having InternalClient inherit AbstractClient directly.
Test Plan:
Run nested KWin, triggered outline (OpenGL case) and debug console (shm case).
InternalWindow unit test still passes.
