Currently, the wayland server updates the server side decoration mode,
which is counter-intuitive, because it doesn't cache the last preferred mode.
With ServerSideDecorationInterface::preferredMode(), it can be simpler.
It's more common to see the parent object being the last argument in Qt
and this way you won't need to specify nullptr parent explicitly if the
xdg-popup or the xdg-toplevel surface doesn't need to be configured
implicitly, which makes tests slightly easier to read.
This commit does away with the special handling of the legacy cursor and
makes it be applied directly in DrmPipeline, using the same state as the
atomic cursor and without dirty flags.
Effect loading is already tested using integration tests, for example
the maximize test verifies that the maximize effect is loaded _and_ it
actually does something useful when a window is maximized or restored,
testScriptedEffectLoader only verifies that the effect is loaded, which
is less helpful than what integration tests provide us.
But perhaps the main problem with these tests is that they require us
building a mockverse around them. This litters code with ifdef
preprocessor directives and makes changing such code a living nightmare.
Another problem with these two tests is that they cannot use OpenGL
because it means mocking OpenGL, which we obviously not going to do.
With integration tests, it's not a problem.
The bottom line is that unit tests can be useful but they make life
notoriously difficult when it comes to testing components that depend on
other components.
The cursor being set out-of-band with atomic commits creates problems
because it can create false positive for atomic tests, if the cursor
state gets changed in between an atomic test and its matching commit.
This commit also ports the cursor to a swapchain instead of only one
image. This is not strictly required but may prevent artifacts and
will be needed for future optimisations.
Currently, kwin expects that the xdg-decoration is installed before the
initial commit. However, decoration tests do that after the initial
commit, which makes testMaximizeAndChangeDecorationModeAfterInitialCommit()
silently pass.
On a second look, it seems that the xdg-decoration spec is okay with the
xdg-decoration being created after the first commit (as long as it's
done before the surface is mapped). This needs to be fixed separately.
CCBUG: 445259
Context properties don't work with QML effects. At the moment, no effect
needs to access the options object, but it makes the QML API consistent.
The workspace is already a singleton type.
The natural geometry can live in a different coordinate space than the
target area. Remove the premature optimization so the cell is properly
placed if the two are in different coordinate spaces.
Currently, the ExpoLayout wants the natural geometry to be in the local
coordinate space because of the default layout mode.
With the natural layout, the ExpoLayout will run a simple loop that
repels overlapping cells.
Once no two items overlap, the items will be scaled down based on their
bounding rectangle and the target area.
The problem is that the ExpoLayout includes the area where items will be
eventually placed when computing the bounding rectangle, which can
result in a sort of a bug where almost all windows are shifted to one
side of the screen, which is not at 0,0.
This change removes the target area from the bounding rect math so the
coordinate space where natural geometry is specified is irrelevant.
It fixes the issue where windows can be shifted to one side of the
screen after adding or removing a window. It also makes the ExpoLayout
API more simpler on the QML side and ensures that no relayouting will be
performed if only the position of the WindowHeap changes.
If the preferred decoration mode changes after the initial commit but
before the surface is mapped, there's a chance that kwin can send a bad
configure event, it's been the case in the past. Add a test to prevent
such cases go unnoticed.
If the decoration is destroyed before the window is mapped, kwin can
respond with a configure event that has 0x0 size. New tests check that
problematic case.
BUG: 444962
Kwin announces a format with alpha when Dma-Bufs are available, even
when the texture doesn't contain any. This results in clients segfault
when trying to access the buffer assuming a maxsize wrt. the announced
format by ways of dimensions and bpp.
This patch moves the format masking to affect the Dma-Buf transport
only.
If eglSwapBuffers() fails, there won't be a buffer and so we need to
mark the frame as failed. Otherwise, the screen can be frozen.
eglSwapBuffers() can fail if some effect calls makeOpenGLContext()
between RenderBackend::beginFrame() and RenderBackend::endFrame(), which
is the case with the zoom effect. It can set wrong draw surface in
ZoomEffect::recreateTexture()

This simplifies focus related logic a bit. Instead of differentiating
between wayland and internal window focus, simply maintain window focus
that works both with regular wayland windows as well as the ones created
by kwin.
The thumbnail that represents the "desktop" in the switcher preview
is taken from the default wallpaper, and it will update automatically
as it changes in future versions of Plasma.
The current one is also added along the other thumbnails as a fallback.

Currently, the test doesn't pass due to Xwayland encountering a protocol
error.
That protocol error occurs because the xdg-output is destroyed before
the wl_output.
This change moves the ownership of the xdg-output to wl-output so they
are destroyed together.
dmabuf-feedback allows the compositor to give the clients better feedback on what
formats and modifiers they should use, and for which device they should allocate.
This way they can reallocate for scanout whenever the compositor tells them to,
which makes direct scanout work for a lot more devices and applications.
KWin handles several types of pointing input devices, e.g. mice,
tablets, etc.
As is, enterEvent and leaveEvent are very ambiguous. This change
prepends "pointer" to those methods to make it explicit that they handle
pointer enter/leave events.
While it could be useful with tiled displays, the isFormatSupported and
supportedModifier functions can be called before prepareModeset, so where
m_formats is still empty. Additionally they're neither in a hot path nor
performance critical.
Whether or not we want to use explicit modifiers for our surfaces doesn't
matter for what format+modifiers drm planes support. This way direct scanout
works by default, without having to explicitly enable modifiers
While a stylus is in proximity we want to show its cursor. In this commit
it only gets shown on move because for a still unknown reason the position
is out of date before the first move event.
BUG: 443921
Ever since the effects were changed to static, each test of the
integration tests includes all the effects. The result of this is that
when doing a debug build each test is now 60MiB or more. With the amount
of tests, this results in ~8 GiB of diskspace used just for KWin's
binary output directory, which is rather excessive.
Since the tests all share a common framework library, we can change that
library to a shared library and that way avoid linking all the effects
into each test.
Most of this is shuffling around some link libraries in the integration
test CMakeLists, however, I needed to export the Xwayland class as it is
used by one of the tests but wasn't exported.
Tracking AbstractOutput properties in Toplevel is not extensible. Since
DecorationItem is the only one who needs Toplevel::screenScale(), make
it track the output device pixel ratio.
Some tests need it, e.g.
FAIL! : TestXdgShellClient::testDesktopFileName() Compared values are not the same
Actual (c->icon().name()) : ""
Expected (QStringLiteral("wayland")): "wayland"
