If eglSwapBuffers() fails, frame scheduling will be broken. KWin can't
recover from that, but still, having a log message might be useful for
the debugging purposes.
This change moves the XRender backend to platformsupport directory,
similar to the OpenGL and the QPainter backend. This allows to put
platform-specific logic in XRenderBackend.
In case hardware transforms can be used again, the shadow framebuffer
must be destroyed; otherwise rendered results will be distorted due to a
mismatch between the dimensions of the shadow framebuffer and the mode
size.
At the moment, the gbm_device for the primary device is destroyed before
the EGLDisplay is destroyed. This results in a crash in Mesa.
In order to fix the crash, this change ensures that the EGLDisplay is
destroyed before the gbm device.
This makes eglSwapBuffers() fail with per screen rendering enabled. In
long term, the screencast plugin has to create its own OpenGL context
and capture window frames after a compositing cycle has been performed.
However, it's currently tricky to do because of monitor screencasting.
Night Color adjusts the color temperature based on the current time in
your location. It's not a generic color correction module per se.
We need a central component that can be used by both night color and
colord integration to tweak gamma ramps and which will be able to
resolve conflicts between the two. The Night Color manager cannot be
such a thing because of its very specific usecase.
This change converts Night Color into a plugin to prepare some space for
such a component.
The tricky part is that the dbus api of Night Color has "ColorCorrect"
in its name. I'm afraid we cannot do that much about it without breaking
API compatibility.
As things are right now, we can only do 32bit textures for dmabuf (see
gbm_bo_format in gbm.h). This means that we were lying to our receivers
when we had 24bit textures by then giving a 32bit texture instead.
This changes it so we request a dummy texture before starting and if we
are offered one we assume they're available and offer a 32bits stream
directly (i.e. BGRA).
The buffer offset for client-side decorated windows is not 0, this plus
mixing the frame position and the client size may result in clipped
thumbnails of client-side decorated applications, such as gedit, etc.

krunner stuff doesn't really belong in kwin, it has nothing to do with
compositing or any other things that are the domain of compositors.
Given that, being as a plugin suits the krunner integration stuff best.
This change introduces basic colord integration in wayland session. It
is implemented as a binary plugin.
If an output is connected, the plugin will create the corresponding
colord device using the D-Bus API and start monitoring the device for
changes.
When a colord devices changes, the plugin will read the VCGT tag of the
current ICC color profile and apply it.
The scripting api is not suitable for implementing all features that
should not be implemented in libkwin. For example, the krunner
integration or screencasting are the things that don't belong to be
compiled right into kwin and yet we don't have any other choice.
This change introduces a quick and dirty plugin infrastructure that
can be used to implement things such as colord integration, krunner
integration, etc.
Without the KWindowSystem integration plugin, Wayland experience will be
negatively affected because windows created by kwin itself won't behave
as desired. Therefore it makes little sense to load this plugin at runtime.
On wayland, we know we're always going to load our internal QPA. Instead
of shipping a plugin and loading it dynamically we can use Qt static
plugins.
This should result in slightly faster load times, but also reduce the
number of moving pieces for kwin.
This also prevents anyone outside kwin loading our QPA which wouldn't
have made any sense and just crashed.
Currently, the OpenGLBackend and the QPainterBackend have hooks to
indicate the start and the end of compositing cycle, but in both cases,
the hooks have different names. This change fixes that inconsistency.
In order to allow per screen rendering, we need the Compositor to be
able to drive rendering on each screen. Currently, it's not possible
because Scene::paint() paints all screen.
With this change, the Compositor will be able to ask the Scene to paint
only a screen with the specific id.
Qt 5.15 introduced new syntax for defining Connections. Fix warnings like this one:
QML Connections: Implicitly defined onFoo properties in Connections are deprecated. Use this syntax instead: function onFoo(<arguments>) { ... }
All platforms that provide support for the QPainter render backend use
per screen rendering. Since there is no any way to test Xinerama-style
rendering, it's better to drop the dead code.
Listen to logind for resume notification and turn the outputs on when it
happens, much like we do when pressing a key.
This way laptops come back on when the lid opens.
