Static plugins being linked with shared libraries doesn't work smoothly.
POSITION_INDEPENDENT_CODE target property needs to be set for
every such plugin. However, there can be targets that we have no control
over, which need POSITION_INDEPENDENT_CODE to be set too. Asking such
projects to add this property and them refusing to do so would be
reasonable because kwin's entire static plugin pipeline is weird.
The test framework was made a shared library because kwin build
directory used to get really big (in 10s of gigabytes).
Due to the -fPIC issues, this change makes the test framework a static
lib again. Obviously, this brings back the big build directory problem.
But, it's not as terrible as it used to be. With this change, kwin build
directory is a couple of gigabytes in debug build, which is a lot but
not as bad as it used to be before.
The InputConfig was introduced to handle tests that don't have valid
kwinApp object. Those tests have been either reworked or dropped, so
let's drop the InputConfig to tidy the config stuff.
Interactions with KScreen cause settings to be reset to the default when the lid
gets closed, so handling lid closing in KWin needs to wait until KScreen no longer
writes configs
BUG: 471282
This change ports the drm backend to the GraphicsBuffer and
GraphicsBufferAllocator.
The main motivation is to unify graphics buffer abstractions across
various backends and to prepare it for output layers, which could be
nicer if we could have direct control over the buffers.
This change makes the EffectsHandler emit the windowAdded signal as soon
as the Workspace::windowAdded signal is received and minimize the
difference between the states observed in kwin core and effects.
The test is flaky. We work around it by passing --repeat until-pass, but
lately even it doesn't help us with this issue.
So skip the test when running it inside KDE CI for a few months until
it gets a newer kernel.
It makes decorations lighter as they don't need to bundle its
configuration logic.
Deprecates the kcmodule property in favour of kcmoduleName which instead
of assuming that the kcm is local to the plugin, it provides the plugin
name to find and load.
The Effects API has one signal screenEdgeApproaching with effects
monitoring the last signal to stay in sync.
If an Edge is destroyed whilst visible, effects currently do not get
notified and it can stay there forever.
This patch emits screenEdgeApproaching if appropriate with a factor of 0
when an edge is destroyed.
BUG: 403354
StrutsTest::testLeftScreenSmallerBottomAligned() used to pass because
one of the previous tests changes the maximize policy to maximize.
A window will be maximized only if it's larger than the maximize area
but smaller than the screen area. That's not the case and the test makes
an incorrect assumption about how X11Windows are placed.
Make the total padding between windows equal to the padding against the
screen borders by applying just half of it on the common borders.
Adjust tests accordingly.

FIXED-IN: 5.27.6
Use CursorSource::image() instead.
Cursor caching in the ScreenCastStream has been changed so
QImage::cacheKey() is not being used. This is rather a preparation for
making kwin grab the contents of the cursor scene.
This change introduces InputDevice::pointerFrame(). The main motivation
behind it is to allow batching multiple pointer events within a single
event frame.
BUG: 454428
Qt requires xcb-icccm 0.3.9. On the other hand, 0.3.9 contains all the
types and functions used by kwin, so remove the corresponding
XCB_ICCM_FOUND checks to simplify the code.
The quick tile test waits 1s to ensure that the quick tile combine timer
is not active. On the other hand, if the active window changes, it makes
sense to reset quick tile combine status. That also lets us get rid of
the QTest::qWait() in QuickTilingTest::testShortcut().
The test used to verify that kwin doesn't crash when ShellClient sets
new geometry. ShellClient used to access decoration borders without
checking whether decoration() is null.
On the other hand, we've added a bunch of new test cases in
testXdgShellWindow, so let's remove this one. If the bug is back, that
test will fail.
This makes it possible to ensure type safety for enums, as each drm property
object can have its own type now, and it reduces the amount of typing needed
to access properties
The test needs OpenGL in order to ensure that the window view effect is
loaded and it registers a screen edge. On the other hand, we could
register a screen edge ourselves and thus allow running the test on
freebsd.
testXdgShellWindow already tests intricate subsurface size changes. The
surface pixmaps are handled differently now too, so the test is not
useful as it used to be 4 or 5 years ago.
Before Deleted merge, it used to be equivalent to waiting until the
window is closed.
This fixes tests waiting until the window closing animation completes
and the Window object is destroyed.
testPointerInput requires OpenGL compositing because it wants to test
cursor push back in the window view effect and the window view effect is
available only if OpenGL is supported.
On the other hand, ScreenEdgesTest::testPushBack() already tests similar
scenario, so let's drop relevant test in testPointerInput to allow
running it when using software rendering.
The virtual backend uses the surfaceless platform. On the other hand, we
move in a direction where the graphics buffer type is explicit, which
creates issues for the virtual backend.
This change ports the virtual backend to gbm so we could manually
allocate dmabuf buffers in order to unify buffer handling in kwin.
Its main drawback is that you won't be able to use the virtual backend
on setups without render nodes. On the other hand, given that the
compositor is meaningless without clients being able to share buffers
with it, it's reasonable to require some way to create and export prime
buffers.
WAYLAND_ONLY will create two tests: one with Xwayland, the other without
Xwayland. This is somewhat wasteful and it results in higher CI times.
On the other hand, Xwayland is started on demand. If a test doesn't need
Xwayland, it won't start.
So let's remove WAYLAND_ONLY in order to lighten kwin on CI resources.
If wayland only tests are needed, we can consider passing the operation
mode to the WAYLANDTEST_MAIN helper, but there aren't such tests afaik.
Window::desktop() is obsolete. On the other hand, X11 doesn't support
having a window on several virtual desktops, so we still need it. As a
compromise, this change moves it to X11Window instead.
Currently, managed and override-redirect windows are split in two types:
X11Window and Unmanaged. While looking at it strictly from type
perspective, this is great. But it creates other problems, e.g. we need
to put shared X11-specific code in the base Window class or mess with
"base" classes.
As an alternative solution, this change merges the Unmanaged class into
the X11Window class and disables some functionality based on the value
of isUnmanaged().
X11Window::manage() is used to create a managed Window. X11Window::track()
is used to create an unmanaged Window.
Currently, the normal window lifecycle looks as follows: create Window,
wait until it's shown, add it to Workspace, wait until it's closed,
create a Deleted, copy properties from the original window to the
deleted one, destroy the original window, wait until the last deleted
window reference is dropped.
There are a couple of issues with this design: we can't nicely
encapsulate X11 or Wayland specific implementation details if they need
to be accessed for closed windows; manual copying of properties is
cumbersome and error prone and we've had a dozen of cases where effects
worked incorrectly because some properties had not been copied.
The goal of this patch is to drop Deleted and extend the lifetime of the
original window, but with a special state set: Window::isDeleted().
The main danger is that somebody can try to do something with deleted
windows that they should not do, but on the other hand, such code needs
to be guarded with relevant checks too.
Workspace::outputAt() casts vectors to four rectangle corners and uses
the shortest one to decide which output is the closest to the given
point.
This works poorly on dual monitor setups where on the left side you have
a monitor with landscape orientation and one with portrait orientation
on the right hand side. In that case, outputAt() will prefer the left
monitor even though the right monitor is the closest one if you cast a
perpendicular from the given point to the right monitor.
In order to improve the handling of that case, this change makes
Workspace::outputAt() compute the closest point to the output geometry
rectangle and use the squared distance as the score.
The indirection contributes unnecessary complexity. The usage of
std::weak_ptr and std::shared_ptr complicates the things further, e.g.

Ideally, same should be done with TabBox and TabBoxHandler, but that can be done in another MR.
Tabbox supports two operation modes: switching between windows and
desktops. Switching between windows is more commonly used. Desktop
switching is not exposed in user settings and it requires some advanced
knowledge of kwin's internals to enable it.
On the other hand, over the past years, we've double downed on effects
like desktop grid and overview to provide graphical means to switch
between virtual desktops.
This change drops desktop switching because it's effectively unused to
simplify the tabbox code, which can be very handy for the future
refactorings of window switching.
Currently windows are scattered in a few separate lists. If you need to
go through the windows, you have to do it piece by piece. On the other
hand, with the overhaul of window types, we've started converging
towards one universal type: Window. Keeping windows in the separate
buckets goes against this design.
Workspace::stackingOrder() already contains all windows. This change
repurposes Workspace::allClientList() from a list of "normal" windows to
all windows, i.e. Workspace::windows(), to be consistent.
There's one API change though. Scripting API will expose other window
types too. This is an intentional change so scripted effects could
operate with all windows. It also matches the current behavior observed
in libkwineffects, which exposes all windows as well.
Instead of having every DrmProperty store pending values, store the data
for the next commit in a separate and temporary type. This simplifies the
code and makes it possible to do commits in a separate thread
Currently Deleted are destroyed with a delay to avoid dangling pointers
within the middle of painting.
On the other hand, it's reasonable to require not to delete windows when
kwin starts painting the screen.
Over the years, we refactored how deleted windows. They are always
unreferenced after finishing the current frame. So it should be fine to
destroy Deleted immediately now.
Qt::AA_UseHighDpiPixmaps has no any effect now.
We used to rely on the fact that Qt::AA_UseHighDpiPixmaps is disabled by
default in Qt 5 in kwin_x11. It's not clear what to do about it now.
It doesn't test anything useful. It's hard to make it test useful things
too due to needing to change the system time. Linking with it also
breaks the encapsulation and it won't work when using MODULE library.
Commit 88cf8355 changed the behaviour of Mali (Lima) / PinePhone devices by disabling GLSL
88cf8355 got backported in 5.27.1 and broke PinePhone devices (White rectangle on topright quarter of a black screen)
This patch restores the behaviour of 5.27.0
VirtualDesktopManager::currentChanged() can be emitted with
previousDesktop being null/0. It can happen only on startup. After that,
it's always valid. In order to make the code that uses the
currentChanged signal less trickier, ensure that the current virtual
desktop is initialized when the virtual desktop config is loaded.
This merges Window::clientMinimized() and Window::clientUnminimized()
signals with the Window::minimizedChanged() signal to simplify some
code.
The avoid animation flag has been dropped because its main usage is to
avoid playing animation during window initialization. But it's not possible
to trigger minimize animation at that moment. API-wise it's better to avoid
having such flags too and rely on surface role to decide whether to play a
given animation.
This signal exists as a convenience helper, but it's not always emitted
as it's advertised to work. Instead of fixing it, let's drop the signal
to simplify virtual desktop code. Its effects can be accomplished by
monitoring Window::desktopChanged() and VirtualDesktopManager::currentChanged()
signals in effects and scripts where needed.
