It's universally supported, and our format negotiation code needs improvements to
properly handle the receiving application not suporting the actual output format
`QRegion::operator|=` has some optimizations but it basically boils
down to
QRegion result(*this);
result.detach(); // it will make a copy because this is shared
result.d->append(rect);
return result;
On the other hand, `QRegion::operator+=` tries to add the new rect
in-place.
Currently, if only blur behind decoration is enabled, no m_windows entry
is going to be created and so the blur effect won't blur the background.
BUG: 479893
Currently the window rule is not 100% effective because the "take focus"
message is not guarded. So depending on the input model of the X11
window, kwin can still activate a window even if it has a window rule
to force no focus.
workspace()->setShouldGetFocus() should be guarded too to help the focus
stealing prevention logic.
Technically though, forcing XSetInputFocus() or WM_TAKE_FOCUS if the
client doesn't advertise supporting them is finiky. But on the other
hand, the window rules are an advanced feature, so its assumed that the
user knows what they do.
The output goes through the following stages when it changes its dpms
mode:
- Output::aboutToTurnOff()]
- some time later, Output::dpmsModeChanged() to indicate that it's off
- Output::dpmsModeChanged() to indicate that it's back on
- Output::wakeUp()
The Output::dpmsModeChanged() signals in the middle are optional. They
may not be emitted after Output::aboutToTurnOff() if the user quickly
cancels the dpms mode transition.
The Workspace should monitor the Output::wakeUp() signal instead.
Alternatively, create the dpms input event filter only after the dpms
mode has changed. While the screen won't be turned back on immediately,
it's still going to produce acceptable visuals. Either solution is fine.
This patch makes the Workspace monitor the wakeUp signal because it
takes fewer lines of code.

The compiler prints the following warning at the moment:
wl-socket.c:143:9: note: ‘snprintf’ output between 10 and 20 bytes into a destination of size 16
When edid parsing fails, KWin will base output settings on the connector, which
isn't great on its own, but at least works in many cases. When the edid can be
parsed later though, the display settings will reset because now the edid identifier
is used to exclude the old config (in which the latter is missing).
To work around that, this commit adds output identification based on the edid hash,
which is also not ideal, but can be safely matched with in case no output config
with a matching edid identifier exists.
This optimizes out an unnecessary atomic test - instead of testing the new state and
then attempting to present with that new state, this just directly tries to present the
full state. If that commit fails, the backend just tries again with the safer presentation
mode.
Replace the hardcoded thumbnails which have a low resolution for
current screen standards (~300x200), with higher resolution ones
(~1200x800).
Also set the new 6.0 wallpaper as the fallback desktop thumbnail

Allow rebinding buttons to send modifier keys (Control, Alt, Meta,
Shift) without any other key.
This is part of restoring the functionality kcm-wacomtablet had under
X11 for wayland.
CCBUG: 461259
Instead of giving the rolling average for render times a special case for
when render time suddenly increases, detect how stable render times are.
If they're volatile and increase a lot, increase the predicated render time
beyond the spike, as more render time spikes are likely to follow.
CCBUG: 477959
vec3() will complain if the vector is not fully initialized. Also if the
type of these variables is changed to vec4 and some miss alpha values,
the glsl compiler will complain again.
This functionally fixes
* duplication of output configuration in ~/.config/kwinoutputconfig.json
* _wrong_ ouput configuration - in particular the scale - being restored (i.e. scale would never be restored)
The textureToTransformMatrix should be applied first, otherwise the scale
transform is going to change the winding order of rotations.
In practice though, it shouldn't matter because these matrices are used
to downscale or upscale uv coordinates.
The redshift table is in gamma 2.2 encoding and not linear, which means
that it only yields correct results with 1.0 pixel values. It also means
that when it's being applied in linear space in the color management shaders,
the result is quite wrong.
To fix that, this commit makes the channel factors linear and the backend
calculates the nonlinear factors where needed.
If the cursor is magnificated and it's slightly moved so the shake
detector returns std::nullopt, the cursor scale will be set back to 1.0
as soon as possible. This is not ideal. Immediately resetting doesn't
help with locating the cursor.
Also the cursor scale reset delay has been increased to two seconds to
provide more time to see the cursor.
First, the texture-to-buffer transform has to be applied, then the y
axis should be flipped. Doing it vice versa changes the winding order
of rotation transforms.
Also the screenshot plugin uses incorrect render transform. Since
convertFromGLImage() undoes the render target's transform, the color
space transformation pass should use the same transform, not the
inverted one.
BUG: 479934
The protocol doesn't have a definition of what it means, but damage is a
flawed interpretation. Color management changes are arguably content updates,
so are viewporter changes, so are blur changes and so on.
