AnimationEffect schedules repaints in postPaintWindow() and performs
cleanup in preScreenPaint(). With the X11-style rendering, this doesn't
have any issues, scheduled repaints will be reset during the next
compositing cycle.
But with per screen rendering, we might hit the following case
- Paint screen 0
- Reset scheduled repaints
- AnimationEffect::prePaintScreen(): update the timeline
- AnimationEffect::postPaintScreen(): schedule a repaint
- Paint screen 1
- Reset scheduled repaints
- AnimationEffect::prePaintScreen(): destroy the animation
- AnimationEffect::postPaintScreen(): no repaint is scheduled
- Return to the event loop
In this scenario, the repaint region scheduled by AnimationEffect will
be lost when compositing is performed on screen 1.
There is no any other way to fix this issue but maintain repaint regions
per each individual screen if per screen rendering is enabled.

They would override KScreen in case we were using a dock station that
brings 2 displays.
We'd get:
- udev: event for the first hotplughed screen
- kwin: process all screens properly (both)
- kscreen: would offer the right configuration for such displays
- udev: process the event for the second hotplug udev event
- kwin: restore the configuration
- kscreen: would think this is a conscious decision and embrace it as a
configuration
With this change we are only re-reading the configuration in case the
outputs changed.
At the moment, despite the protocol supporting it, we were not feeding
the EDIDs. KScreen was falling back to the output name so it didn't fail
horribly but it's still a good idea to provide all the data.
Prefer replacing then deleting the selection to the other way around.
This way less events need to be reported and the clipboard manager
doesn't get confused.
At the moment there was a race condition when putting something into the
keyboard from XWayland apps. The clipboard manager would announce a new
thing before we'd submitted it all resulting in a broken state.
This change detects when it's fetching and will only refresh the source
after everything has been sent.

The sliding popups effect schedules a repaint and then unreferences the
deleted window. The problem with doing so is that the scheduled repaint
will be effectively discarded because the Deleted will be destroyed once
we are back in the event loop.
This issue is most noticeable on Wayland. Not sure why. If you close
Kickoff, you may see its flickering ghost in background.
If it happens that a Deleted has a pending repaint, transform it into a
workspace repaint to avoid discarding any scheduled repaints.
When dragging files on the desktop, the cursor image might be just too
big for the cursor plane, in which case we need to abandon hardware
cursors for a brief moment and use a software cursor. Once the files
have been dropped and the cursor image is small enough, we can go back
to using hw cursors.

Currently, the method `createErrorReply()` with empty strings
errors out and the client gets no answer:
```
QDBusConnection: error: could not send error message to service "":
Error name cannot be empty
```
Simple test:
qdbus org.kde.KWin /KWin org.kde.KWin.showDebugConsole
qdbus org.kde.KWin /KWin org.kde.KWin.queryWindowInfo
Error name uses D-Bus Interface-like notation as suggested in
https://doc.qt.io/qt-5/qdbuserror.html#name

We use the GL_LINEAR magnification filter. This means that GL_REPEAT
wrap mode cannot be used for the software cursor because sampling texels
beyond the right texture edge is the same as sampling texels on the
left edge. This may produce undesired visual artifacts.
Only set the model value when the user explicitly interacts
with the control.
This fixes a bug where some detected properties (position
and size) were not fully applied due to the the binding loop.
Currently, if there is no pointer, only the hardware cursor will be
hidden. If the software cursor is forced, you are going to see a dead
immovable cursor.
If an output is rotated, we will compute a transform matrix for the
cursor plane to rotate its contents.
In order to compute that matrix we need the rect of the cursor in the
device-independent pixels, the scale factor and the output transform.
The problem is that we provide a rect of the cursor in the native
pixels. This may result in the cursor being partially or fully clipped.

XdgSurfaceClient tries to avoid sending unnecessary configure events,
but in some cases, the compositor has to send one even if the surface
state hasn't changed, for example in response to a set_maximized()
request, etc.
This change introduces a special flag to indicate that the scheduled
event has to be sent no matter what.
If you play some video and the software cursor doesn't hover it, then
the shadow cast by the cursor will be getting darker and darker with
every frame.
The main reason for that is that kwin paints the software cursor even
if the rect behind it hasn't been damaged or repainted.
If a cursor animation is driven purely by frame callbacks and kwin
uses hardware cursors, the cpu usage may spike to 100%.
This change addresses that issue by sending frame callbacks after a
compositing cycle has been performed.
That commit broke CI's build, while it's building fine locally.
Let's revert it until having a better understanding of the cause.
Also revert the attempt to fix it, which didn't succeed.
This reverts commit 9cbac6fe3a.
This reverts commit 3e15f64055.
Include header "rulebookdata.h" instead of class forwarding.
The header is automatically generated by kcmutils_generate_module_data
and includes a namespace
GLTexture::width() and GLTexture::height() return the size of the cursor
texture in native pixels, but we need a size in device independent pixels.

Only a subset of KDE applications (part of KXMLGUI ones) support
this setting, and on the other hand non KDE applications
may support it as well.
As there is no way to identify the subset of affected applications
not even with technical terms, make the description a bit more
generic, leaving it open to future improvements to the set of
supported applications.
Previously seat interface was keeping track of the repeat information,
but now it is taken care by KeyboardInterface, which is created only if
the setHasKeyboard is set to true.
So, since we are setting up various capabilities on seat in libinput,
re-parse configuration here, so that various information like key repeat
is notified to kwayland-server
BUG: 428039
On Wayland, a surface must be displayed the same way no matter how the
attached buffer is transformed. In order to guarantee that, we build the
surface-to-buffer matrix, which is used to compute the texture coords.
The surface-to-buffer matrix represents an affine transformation. Thus,
performing linear interpolation between texture coordinates won't end up
in corrupted rendered results. This is the main assumption that we make
during generation of contents window quads. After creating a sub-quad,
the new quad's texture coordinates are computed by interpolating between
the source quad's texture coords.
However, WindowQuad::makeSubQuad() makes a concrete assumption about the
order of texture coords, which might be false if the attached wayland
buffer is rotated 90 or 270 degrees.
This issue went unnoticed after merging the viewporter patches because
the developer who was working on it had been using primarily nested
kwin_wayland for testing purposes. And it appears like kwin schedules
full screen repaints even though it supports buffer age. It still needs
some investigation why that happens.
BUG: 428003
Qt checks OpenGL version to determine if some features can be enabled.
This change ensures that the format EGLPlatformContext returns has
properly initialized the OpenGL version, the context profile and the
format options (e.g. whether it's a debug context, etc).
