Due to being a compositor, kwin has to conform to some certain
interfaces. It means a lot of virtual functions and function tables to
integrate with C APIs. Naturally, we not always want to use every
argument in such functions.
Since we get -Wunused-parameter from -Wall, we have to plumb those
unused arguments in order to suppress compiler warnings at the moment.
However, I don't think that extra work is worth it. We cannot change or
alter prototypes in any way to fix the warning the desired way. Q_UNUSED
and similar macros are not good indicators of whether an argument is
used too, we tend to overlook putting or removing those macros. I've
also noticed that Q_UNUSED are not used to guide us with the removal no
longer needed parameters.
Therefore, I think it's worth adding -Wno-unused-parameter compiler
option to stop the compiler producing warnings about unused parameters.
It changes nothing except that we don't need to put Q_UNUSED anymore,
which can be really cumbersome sometimes. Note that it doesn't affect
unused variables, you'll still get a -Wunused-variable compiler warning
if a variable is unused.
There were overflows in the bandwidth estimation calculation. To simplify things,
also only generate common modes if the display doesn't advertise them on its own
already.
Seems we can't have a plural with an argument in singular and not in the
plural
a format specification for argument 2, as in 'msgstr[0]', doesn't exist in 'msgid_plural'
msgfmt: found 1 fatal error
Makes it possible to follow the dbus service for locale configuration,
making it possible to have third parties integrate with Plasma.
This is done opt-in for now, it can be adopted generally in the future,
if necessary.
This rewrite ensures that
- formats are tested for multi-gpu transfer
- dmabuf with either 10bpc or 8bpc buffers are preferred to cpu copy
- formats where drmModeAddFB2 fails are skipped
kwin can crash for reasons that have nothing to do with compositing. If
that's the case, after two crashes compositing will be permanently
disabled and you would need to go to system settings to reenable it, the
timestamp based check in the x11 backend won't be effective.

We don't need to emit {x,y,width,height}Changed signals ourselves. We
also need to send an expose event otherwise the window can be rendered
incorrectly if it's resized. The logic follows QtWayland implementation.
With the pull approach, the XdgOutputV1Interface class doesn't have to
be exposed in the public api and can be made private to simplify the
implementation of the xdg-output-v1 protocol.
Currently, kwin will continue matching dnd actions after a drop. This is
mainly needed in order to make "ask" action work.
However, it appears like there are clients in the wild that update offer
actions after receiving wl_data_source.dnd_drop_performed and wl_data_device.drop
events.
One could argue that's a client bug, and perhaps it is, but the spec is
vague about that. In meanwhile, let's make sure that dnd action matching
is active after drop only when the selected data source action is "ask."
KPluginMetaData in KF 6 doesn't load desktop files anymore. It means
that plasma packages need to come with json metadata files.
This change adjusts the generic scripted config loader so it can load
configuration even for packages with no metadata.desktop files.
As the drm format number of 10 bit colors is lower, the fallback sorting
preferred those formats, even if KWIN_DRM_PREFER_COLOR_DEPTH=24 was set.
To fix that, prefer 8 bit colors over something random.
The X11 standalone backend has an obscure fallback to hw screen
inversion if compositing is disabled. While it's great, it conflicts
with existing features such as night color.
In order to make code cleaner and clean up dependencies, this change
moves screen inversion shortcut to the invert effect. While it can
potentially affect users that don't use compositing, I think the number
of such affected people is very small.
In hindsight, preferring hw over sw transform is nice, but I think we
need to analyze it first and then come up with a proper solution that
integrates with color management and works great both on x11 and wayland.
The entire approach behind that test is wrong. Even slight changes in
one pixel can make the test fail. There's no human-friendly way to
determine what the difference between reference and actual frames are.
The reference frame is generated in code rather than from an image on
the disk, which makes the tests even more error-prone.
The test is flaky too and constantly blocks merging patch submissions.
We need a different way to test rendering results, not what
testSceneQPainter currently does. Normally, I would say that we need
to add such an infrastructure before dropping the test, but it makes the
merging process so inconvenient and the test doesn't really bring any
value, it tests really basic cases which are noticeable right away after
launching kwin.
renderWindow bypasses all other effects and simply calls the code that
is responsible for the final render of the window. This means that any
effects that are active on the window are skipped, including things that
may change how the window is rendered like the invert effect. To fix
that, ensure we render the window with all effects applied.

The screen needs to stay black until it gets enabled again, otherwise
slight timing differences can cause the screen to turn on full brightness
again immediately before turning off.
