OutputTransform::Normal is handled by doGrabTexture().
If the texture transform is neither normal nor flip-y, the GPU is going
to be used to transform the texture, however since it doesn't flip the y
axis, doGrabTexture() will flip the y axis on the cpu side. To fix that,
make the contents of backingTexture mirrored vertically.
Opaque is a QRegion in logical pixels, using .toRect will round to the
nearest integer in either direction. This can mean an area is considered
opaque outside the rendered area, leading to glitchy contents on
shadows.
This is most noticable on on X11 windows when fractional scaling is
used.
Long term I hope to move Item::opaque to QList<QRectF> and
WindowPrePaintData::opaque to device pixels.
QWindowSystemInterface goes via QGuiApplication which updates some
internal properties. Most notably QGuiApplication::lastCursorPosition
which is used by advanced menu closing behaviour.

otherScreenThumbnail is used to fake a window thumbnail being dragged
half in the old screen, half in the "new" one (or even more than two)
right now the condition to use it is purely the "real" thumbnail x
or y change, but sometimes especially when the item has just been created
and is being laid out it might trigger an itemDraggedOutOfScreen
when no-one was dragging.
We should never make otherScreenThumbnail visible when we aren't dragging
a thumbnail, so check for Drag being active in the source item.
the item will be kept visible even if drag becomes inactive as before,
as it still needs to be visible for the reset animation

By default the translation domain of KQuickManagedConfigModule is the
unique identifier within the namespace of the plugin, but those i18n
strings belong to kwin.po.
Though there are 3 common CVD types, each individual can have different
color perception level, and the default intensity might not be suitable
for everyone, so add an intensity slider to select how much the filter
affects the display.
Modifiers for global shortcuts are handled differently from normal shortcuts,
because they need to consider modifiers that are consumed by xkb for keyboard
layout transitions and similar. This restriction is not relevant for custom
tiling.

SeatInterface currently has a separation of kwin's focus scope to
pointer input with early return guards in notifyPointerEnter and
notifyPointerLeave where clients don't get pointer events.
However we don't update the initial state when a drag is started, this
patch notifies sends a pointer leave to the new drag target before the
data_device enter so things are consistent.
This also brings it in line with Weston and Mutter.
notifyPointerLeave has it's early return removed as for wayland windows
as we know nothing will have pointer focus.
Instantiators create objects when they're added to a model, and
deference when when they're removed from the model.
When we explicitly set a parent in onObjectAdded we're creating a second
reference. This does get cleaned up later, but not in the same frame.
This brings us in line to what QQmlRepeater (which works with items)
does internally for items being added and removed.

Reducing approachGeometry is not needed.
During edge creation, createHorizontalEdge and createVerticalEdge
already substract the needed cornerOffset, and edges reserved by client
windows shouldn't be reduced in geometry.
In addition, during display, ScreenEdgeEffect confines the painted area
to approachGeometry. So approachGeometry shouldn't be reduced in
advance.

The original assumption was that once PointerInputRedirection starts
pushing cursor sources to cursors, they cannot be null. In many cases,
it is true, but the tests are a bit special as many of them lack
wl_pointer.set_cursor requests, so it's possible to set a null source.
As an example, when the pointer moves from the decoration to the
surface. On the other hand, it also does make sense to allow having
no source connected.
While tabbox switching is usually a keyboard operation, we offer also
a mouse-friendly way to launch it via screen edges, and should allow
to switch directly on mouse click.

The blur geometry is scaled in the global coordinate space, while it
works fine with integer scale factors, it's not okay with fractional
scale factors as it doesn't match how the ItemRenderer snaps quads to
the pixel grid.
Note that blur behind apps can be still off by one pixel, but it
should be harder to notice it. In order to fix it, it would be great
to apply effects behind Items, which is on my todo list.
Window::layoutDecorationRects() uses KDecoration2::Decoration::rect() to
get the bounding decoration rect.
While Decoration::rect() should normally match Window::rect(), they can
diverge for a brief moment during async geometry updates. The worst
possible case is that the cached item quads may not be invalidated when
the geometry updates saddle.
To fix that, make DecorationItem monitor decorated client size changes
instead of window frame geometry changes. The reason for that is that
Decoration::size() is effectively decorated client size with added border
margins.
Wine/Wayland hides the cursor as follows:
[ 853107.473] -> wl_pointer@15.set_cursor(172832, wl_surface@38, 0, 0)
...
[ 858989.757] -> wl_surface@38.destroy()
[ 858989.759] -> wl_pointer@15.set_cursor(172832, nil, 0, 0)
i.e. it destroys the cursor surface, then calls wl_pointer.set_cursor().
SurfaceCursorSource stores the wl_surface in a QPointer, furthermore it
is going to emit the changed signal, which is needed to force the
CursorItem to update its content, only if either a new hotspot or a
surface has been passed to SurfaceCursorSource::update(). So what happens
is the following:
- The SurfaceInterface object is destroyed and the QPointer resets its
value to nullptr
- SurfaceCursorSource::update(nullptr, QPointF(0, 0)) gets called in
response to wl_pointer@15.set_cursor(nil, 0, 0)
- but since m_surface has been implicitly reset to nullptr, no changed
signal is going to be emitted
This change addresses the issue by making the SurfaceCursorSource track
the SurfaceInterface's destroyed signal.

Views are owned by the C++ backend, but also retrievable by invokables
to get neighbouring screens from JS space. By default Qt then transfers
ownership of the view to the QML collector. This results in double
ownership.
BUG: 480788
Window::checkWorkspacePosition() before the window is mapped is still
problematic and should be avoided as it can produce undesired constrained
client size (1x1).
Given that XdgToplevelWindow tries to maintain the same frame geometry
size, it should be enough to schedule another configure event instead.
It is going to be in line with the other decoration logic in the
XdgToplevelWindow and it's a better way to handle async geometry updates.
