Summary:
Compositing is suspended/finished in a very hard way fashion, effect
windows are destroyed without notifying effects about it.
AnimationEffect tries gracefully release deleted windows, but because
in some cases(like when suspending compositing) a deleted window can
be already destroyed, a segmentation fault can happen.
This change adjusts the order in which effect windows and effects are
destroyed, so AnimationEffect (and other effects) cannot access dangling
pointers.

Summary:
We don't really have to have two different code paths for group
transients and ordinary transients. For now, AbstractClient::hasTransient
is good enough to check the relationship between potential parent and
the transient.
In long term, we need to "invert" the relationship, instead of checking
whether given parent window has a transient, we should check whether
given transient is a transient for a given window so we can keep Deleted
transients above their old parents.

Summary:
This problem appears if shadow corner tiles are too big and
some window has size smaller than 2 * shadowTileSize.
This change tries to address the problem above by exclusing
overlapping tile parts. If there are any two overlapping corners
then tile between them(top/right/bottom/left) is not rendered.
Also, because some corner tile parts can be excluded, corner tiles
are expected to be symmetrical(i.e. if we remove right half from
the top-left tile and left half from the top-right tile and
stick them together, they still look fine, there are no misalignments, etc).
Most shadows(e.g. shadows from Breeze) have such behaviour.
No tiles are overlapping

Summary:
If the cursor theme failed to create KWin crashed due to an endless
recursion. There are two reasons for this fault:
1) When the physical size does not exist we perform a division by 0
which results in an invalid size going into wl_cursor_theme_load
2) We emit the signal that the cursor theme changed even if it didn't
change thus creating an endless recursion
This change addresses both problems: it checks that the size is not 0
and changes the handling for theme update to only destroy the previous
theme if the new theme could be created and only emits the signal if
things change.

With Wayland KWin needs to provide certain services, which were provided
before that by the Xserver. One of these is gamma correction, which includes
the - by many people beloved - functionality to reduce the blue light at
nighttime. This patch provides the KWin part of that. It is self contained,
but in the end will work in tandem with a lib in Plasma Workspace and a KCM
in Plasma Desktop, which can be used to configure Night Color.
* Three modi:
** Automatic: The location and sun timings are determined automatically
(location data updates will be provided by the workspace)
** Location: The sun timings are determined by fixed location data
** Timings: The sun timings are set manually by the user
* Color temperature value changes are smoothly applied:
** Configuration changes, which lead to other current values are changed
in a quick way over a few seconds
** Changes on sunrise and sunset are applied slowly over the course of few
minutes till several hours depending on the configuration
* The current color value is set immediately at startup or after suspend
phases and VT switches. There is no flickering.
* All configuration is done via a DBus interface, changed values are tested
on correctness and applied atomically
* Self contained mechanism, speaks directly to the hardware by setting the
gamma ramps on the CRTC
* Currently working on DRM backend, extensible to other platform backends in
the future
* The code is written in a way to make the classes later easily extendable to
also provide normal color correction, as it's currently done by KGamma on X

Summary:
The test DontCrashUseractionsMenu (Waylandonly) found an issue in our
screen handling implementation in the QPA. The code exposed a short time
frame between the dummy screen getting destroyed and the first screen
being added. This could result in a crash of KWin.
There is actually no need to implement Screen on top of Wayland screen.
KWin has all the knowledge, so we can also base this on top of the
Screens API.
Advantages:
* no delays due to Wayland roundtrips
* handle screen getting removed (was a TODO)
* handle resolution changes (was a TODO)
The new implementation has a disadvantage that it destroys and readds
all screens whenever something around the screen changes. This shouldn't
be an issue in practice as it's only for the internal QPA and thus only
affects KWin internal windows which is placed in global coordinates
anyway. If it turns out to be a problem we need to track better the
screen changes - so far those were not tracked at all.
Test Plan: Run a few unit tests which change screens

The integrationTest function takes a new optional argument whether the
test supports a Wayland Only mode. If that's the case the test is
compiled twice, once (as always) as "foo" with XWayland support and
once as "foo_waylandonly" without XWayland support.
This way we can ensure that our code always supports both modes. The
tests found multiple issues. At the moment fast running tests are
sporadically crashing on tear down. This needs further investigation.
A new test class for KWinBindings added which is intended to group the
testing of the various slots set up in kwinbindings.cpp. As the scripts
also delegate to the slots this is also tested.
Summary:
This is a regression due to changes in Breeze to support Qt 5.8+ behavior
change. KWin's own QPA operates like < Qt 5.7 and breeze was programmed
against that. Due to that it can happen now that Breeze hits code paths
in which KWin does not have a surface.
To trigger one only needed to open the user actions menu twice.
This change adds a test case which simulates the problem and fixes all
crashes happening in the code path.
Most likely shadows are now broken for KWin's own windows, this change is
only to prevent the crash and thus is for 5.10 branch, while shadow
fixing will go to master branch.

by kwinApp, just like the normal kwinrc. The KSharedConfigPtr is now
passed to Xkb.
As a nice side effect this makes it easier to test keyboard layout
changes as we can now properly mock the keyboard configuration. Thus
this change also comes with an autotest for loading keyboard layout
configuration. This is becoming more and more a need as we start
getting bug reports for layout specific issues like global shortcuts
not working with Greek layout.

Summary:
There are two types of constraints supported:
1. Pointer confinement
2. Pointer locking
In the case of confinement the pointer is confined to a given region of
the surface. This is comparable to general operation where the pointer
is confined to the screen region.
In the second case the pointer gets locked. That means it cannot move at
all. No further position updates are provided, only relative motion
events can go to the application. There is a hint about cursor position
update on unlock which is not yet implemented in KWayland::Server, thus
also not in this change.
The implementation in KWin grants the requests for pointer constraints
when the pointer enters the constrained region, either by pointer
movement or by e.g. stacking order changes. There is no confirmation
from user required to enter that mode. But we want to show an OSD when
the pointer gets constrained, this is not yet implemented, though.
Breaking an active constraint is relatively easy. E.g. changing the
stacking order will break the constraint if another surface is under the
cursor. Also (in case of confinement) moving the pointer to an
overlapping window breaks the confinement. But as soon as one moves the
pointer back to the window a constraint might get honoured again.
To properly break there is a dedicated event filter. It listens for a
long press of the Escape key. If hold for 3sec the pointer constraint is
broken and not activated again till the pointer got moved out of the
window. Afterward when moving in the pointer might activate again.
The escape filter ensures that the key press is forwarded to the
application if it's a short press or if another key gets pressed during
the three seconds. If the three seconds way fires, the later escape
release is not sent to the application.
This basic interaction is also ensured through an added auto test.
This change implements T4605.

CCBUG: 323798
New test case to verify that global shortcut triggering works correctly.
First test case is to verify that consumed modifiers do not break the
shortcut. E.g. a shortcut registered for % should trigger on Shift+5 on
us layout. For that the modifier needs to be consumed, otherwise it's
Shift+% and doesn't trigger. As the test shows this is currently the
case.
Each test needs a dedicated dbus session as the test needs to register
services (e.g. kglobalaccel) and might fail if that cannot be registered.
Due to the wrapping in another command the test need to make sure that
any process they start terminates before them. E.g. the activities test
must stop kactivitymanagerd in cleanupTestCase, otherwise the test times
out.
New test infrastructure which supports testing window rules at runtime.
Test exposes problem of window rules not able to match window roles in

CCBUG: 367554
This test verifies the functionality of modifier only shortcut
activation. The base test case uses a helper object which is exported
to DBus and has a slot which can get triggered.
The test configures the individual modifiers to call that DBus method
when the shortcut is triggered. It simulates pressing the modifier and
verifies the DBus method was invoked or not.
Verifies the condition from D1982 with expected_fail. That is sets
a Client on non existing activities and expects that it should be on
all activities.
Summary:
Plasmashell's desktop windows are RGBA which forces the compositor to
perform blending and render the background. That is absolutely pointless
as there is no window behind the desktop window it could blend to. All it
does is destroying KWin's more optimized code path and forcing additional
rendering which will never be visible (including shader push/pop).
With this change KWin forces desktop windows (both X11 and Wayland) to
be considered as opaque by setting the depth to 24. Thus blending is
disabled and the background is not rendered.
Test Plan:
Verified with apitrace that KWin goes in the opaque rendering
path for desktop windows.

When the edge is triggered showing desktop is activated.
Summary:
KWin needs to support restarting the OpenGL compositor in case of a
graphics reset event.
On Wayland the tricky part is that the applications should not notice
this. Most importantly KWin cannot just destroy the EGLDisplay and create
a new one. But this is how a restart works: the complete compositor gets
torn down and recreated - including the EGLDisplay.
This change moves ownership of the EGLDisplay to the Platform.
The AbstractEglBackend subclasses query the Platform whether there is
already an EGLDisplay. Only if there is no EGLDisplay the EGLDisplay is
created and only if no EGLDisplay is registered with Wayland the bind
is performed.
Another change is regarding the destruction: the AbstractEglDisplay does
no longer unbind the Wayland display and does no longer destroy the
EGLDisplay. The EGLDisplay is destroyed by the Platform - so very late
on application exit. The Wayland display is unbound when the Compositor
terminates.
Test Plan:
Limited testing with the added auto-test. This one needs to
be extended to fully verify that OpenGL applications continue to work.
But this requires build.kde.org to support OpenGL on Wayland.

Summary:
Most platforms like the nested and virtual do not handle the outputs
themselves and WaylandServer announces the Outputs to Wayland.
So far this was static: at startup it got announced once to Wayland
and any changes were not catched.
This change makes WaylandServer listen to changes to the Screens and
sync them to Wayland.
Unfortunately KWin's internal Screen information is not sufficient to
properly synchronize this to Wayland and also Wayland by not supporting
adding/removing modes does not help.
Thus the solution implemented here is to add new outputs reflecting the
changes and then removing the old ones. This creates situations with more
outputs being present than actually there, but prevents that there are
no outputs at all.

Summary:
The idea behind this autotest is inspired by bug 356328 which produced
incorrect rendering results. Also it's inspired by openQA which performs
image reference comparisons.
This test case tries to go further. It creates reference images which
must match the rendering result exactly. So far the test case verifies
the start condition - kwin started and one frame is rendered with default
cursor in the middle of the screen. And it verifies the moving of the
cursor without any windows shown. Whenever the cursor moves a repaint
should be triggered and the old and new area should be properly
repainted.
To support this the test needs some minor changes in KWin:
* Scene provides a frameRendered signal - needed for waiting on frame
* Scene and SceneQPainter are exported
* SceneQPainter provides access to it's Backend, so that we get to the
backbuffer
* ScriptedEffectLoader is exported for getting a list of all scripted
effects - (we don't want fade to manipulate the rendering)
