Otherwise, prePaintPass, postPaintPass and possible future overhead like overlay
plane matching aren't accounted for, which can cause frames to be dropped.

While they are harmless, they can result in the client repainting more
than needed and resulting in the opposite edge "bouncing" when resizing
the window.
Initialize X11Window::m_client geometry with a proper value so, later, the
X11Window::configure() function can properly determine whether the client
window is resized.
NETWinInfo queries the window state and setState() will do nothing if the
proposed new state matches the cached server side state.
On the other hand, given how the test is structured, there can be pending
fullscreen changes on the kwin side that are yet to be sent to the X server
when the NETWinInfo object is created.
This change fixes that race condition by adding an explicit Xcb::sync().
Some clients (like xdotool) can send multiple events for the same
key. In some instances the number of presses and releases can even
be mismatched leading to stuck keys. While we clean up pressed keys
when the client vanishes, this doesnt help when it doesnt immediately
disconnect (for example Xwayland keeps client connections live
longer than the actual x client to reuse them).
Also fixes a copy paste mistake where key presses where also written
to buttons.
This avoids regressing compared to PowerDevil in 6.1 which also
protected against setting internal display brightness to 0.

It's completely unused. If brightness modification is desired for night light
for example, it should be tied in with the actual brightness controls for outputs
instead
With programmable LUTs, consecutive transfer functions, inverse transfer functions and
multipliers can all be combined into one LUT. This allows offloading operations in more
situations and makes the operations more efficient too, as potentially fewer LUTs have
to be programmed
This is useful for autotests and some other special cases where we need to calculate
the result of a color pipeline on the CPU. Long term, this should replace
ColorDescription::mapTo
When the GLX or the EGL backend is destroyed, it is going to reset the
RenderLoop state, including the number of frames in flight. It does so
because of the historical reasons. At the time, there was no output frame
object to track the lifecycle of a frame.
After introducing the OutputFrame and hooking it into the RenderLoop,
the pending frame count will be reset automatically in RenderLoop when
the GLX or the EGL backend is destroyed. But we forgot to remove
the invalidate() function calls. So, when the GLX backend goes down, it
resets the pending frame count to zero and then it destroys the pending
OutputFrame object, which would result in decreasing the pending frame
count by 1 and triggering an assert in the RenderLoopPrivate::notifyFrameDropped()
function.
Since there is the OutputFrame helper now, the invalidate() function
can be dropped. Technically, the invalidate function did more than just
reset pendingFrameCount to 0, for example also stop the compositeTime.
But that should be fairly harmless new behavior.
Switching to triple buffering requires dropping a frame, so if we constantly
switch back and forth between double and triple buffering, that can cause
very visible performance issues

sched_setscheduler() is implemented as a stub in musl that does
nothing because Linux provides no way to set scheduling parameters
per process.
Use pthread_setschedparam() to change the scheduling parameters of
the threads instead.
BUG: 487996
Wayland specification is that the compositor chooses the actions based
on keyboard modifiers rather than the application initiating the drag
being told the modifiers.
Some distributions do not wish to build the KWin X11 backend as
they do not use it, even though they wish to maintain X11 support
for Xwayland when using KWin as a Wayland compositor.
Allow this choice by splitting the build flag and setting it up to
forcibly disable building the backend when building X11 code is
switched off.
These were off by one because the surface tab was removed.
Insetad of numbers look up the indices of the widgets so its
less prone to break in the future.
Apparently the night light kcm allows to set the custom times so the
evening is earlier than the morning to handle extreme cases close to
the North and the South pole.
NightLightManager::updateTransitionTimings() should require no changes.
BUG: 489366
With recent change of using show desktop with plasma's edit mode,
wayland input method becomes unusable when trying to type in the search
box of widget explorer. This is because the input method window will
currently break showing desktop under wayland.
Under X11, an input method window is traditionally implemented as an
override redirect window. Under Wayland, the window should be treated
similarily, but now we have a special type for input method window.
