At the moment, the keyboard interception code in the effects system
relies on Qt code processing key events. However, since QDesktopWidget
is removed in Qt 6, this is a blocker for Qt 6 port.
This change ports the X11 backend to private xkb keymap as indicates in
the todo comment. It allows us to drop the last QDesktopWidget usage.
SlideDocks option was added after receiving negative feedback about
sliding docks. SlideBackground option was added to provide smooth
transition path for old users.
In hindsight, adding SlideDocks option was a mistake. It provides
excessive configurability in exchange for more code complexity.
With the virtual backend, it makes more sense to create outputs on
demand. It makes code clear, it would be also nice to use the virtual
backend for virtual outputs rather than have every backend implement its
own virtual outputs.
Qt 6 insists on this being exported, which in turns fails as this is
actually not implemented. There seemingly is an implementation, but that's
in a different namespace, so this can never have been used from the
outside anyway.
Currently, windows are not highlighted as expected in the window view
effect if the keyboard focus belongs to another screen view.
In general, it makes more sense to apply "Window.window.activeFocusItem"
constraint only to heap.selected.
With DamageReportNonEmpty damage report level, the x server will
send kwin a DamageNotify when the damage region changes from empty to
not empty.
The damage region will be made empty when SurfaceItemX11 calls
xcb_damage_subtract().
It appears like xcb_generate_id() can return us an already associated
XID, which eventually results in xcb_damage_subtract() failing and
breaking state tracking in SurfaceItemX11. KWin will no longer receive
DamageNotify events and some windows will freeze.
In order to make getting BadIdChoice less catastrophic, this change
makes the SurfaceItemX11 reset m_isDamaged after successfully fetching
the damage region. If xcb_generate_id() returns us a bad id, kwin will
try to fetch the damage again in the next frame.

This change extends the OutputChangesTest so it also covers the cases
where a maximized and a fullscreen window is moved back to its original
output when it's hotplugged.
It makes no sense to play the animation if the window is invisible. It
can also produce unexpected results if the window is not on current virtual
desktop as animate() will temporarily force the window to be visible.
If an invisible window is animated, e.g. minimized window, the maximize
effect will temporarily make it visible in order to play the animation,
which is unexpected.
Activities are loaded async. During this time any fetch of activity
information is incorrect as we will treat any settings as invalid.
We need to ignore attempts to set activities during this time, but also
refresh Window's concept of activities once we are loaded.

Display::outputsIntersecting() computes the logical geometry using the
oriented mode size and the scale factor, but OutputInterface's scale
factor is ceil()ed up, so the resulting logical geometry can be incorrect.

X/Y/Width/Height all get changed in the polish event so this only has
any effect in bindings before the first frame.
It seems this was leftover from development where we didn't have initial
values synced up properly.
This removes the "OpenGLIsUnsafe" flag and replaces it with a timestamp
that we can check to see how long ago we tried enabling compositing, so
we can retry it if a certain amount of time has elapsed.

The drm fd can get stuck in readable state, in which case the
QSocketNotifier will fire the activated signal as often as it can
leading to high cpu usage.
We need to read() the drm fd in order to make the socket notifier stop
firing QSocketNotifier::activated.
This change removes the m_platform->isActive() check to ensure that
drmHandleEvent() gets called, in general, it should be safe as we only
notify the outputs about completed pageflips.

With this change, when the specified output is disconnected, it will
just behave as if none were selected but when it's connected again it
will pick it back up.
