`bottomLeft()` is affected by the same issue as anything else using
bottom, that is, it is off by 1. So instead use top() + height() for the
bottom edge.
This behavior was added in order to fix a crash reported in bug report
442990. However, the analysis was not 100% correct, kwin failed to
create a placeholder because the relevant check was incorrect. The drm
backend was checking the list of all connected outputs rather than the
list with enabled outputs to decide whether to create a placeholder output.
As a safety measure the proposed behavior makes sense, however the drm
backend is not the right layer to implement it. If the last enabled
output is disconnected, kscreen should view it as a new output
setup and re-enable outputs in order to ask user what desired output
configuration should be.
This port the remaining bits in EffectsHandler from Screens. It does
make sense to deprecate or remove workspace geometry bits in
libkwineffects as the interpretation of the workspace layout is very
effect-specific, e.g. as in the slide effect.
Without this, the rowsChanged signal wasn't emitting at startup, so the
binding `highlight: kcm.desktopsModel.rows !== 2` didn't work correctly.

The guessed repaint region is not optimal on wayland. Second, if it's a
new output, it's expected that there will be already a scene repaint
that covers all items on the given output so items don't need to provide
redundant repaint region.
The kernel doesn't disable connector objects that represent physical ports
when the output gets removed. If KWin tries to change the output configuration
without explicitly disabling the connector, atomic commits can fail.
- use kcoreaddons_add_plugin CMake macro, the other one is KWin internal
- reference embedded json metadata in section about macros
- Provide codesnippet to json metadata
- Do not explicitly define plugin id in metadata, instead we can derive it from the library name
Sometimes windows on other desktops are higher in the stacking order,
which causes them to unexpectedly jump above windows from the current
desktop in the effect.
To fix that, the z index is adjusted to be higher for windows on the active
virtual desktop, and windows from other desktops get reduced opacity in the
beginning of the animation
When we render individual component of a decoration into an atlas we
ceil the positions for the individual component parts so they don't risk
overlapping. See SceneOpenGLDecorationRenderer::render
This isn't done when we set the overall texture height. This can cause
the bottommost part of the atlas (the right edge) to go out of view.
BUG: 453745
xdg_wm_base is a global that with a single instance in our high level
wrapper. Our surface wrapper needs to get the xdg_wm_base::Resource
instance on occastion.
Currently we go via wl_client for the mapping, but this breaks down
should a client bind wm_base twice.

To allow for easier testing in development and for debugging purposes, when
the KWIN_IM_SHOW_ALWAYS environment variable is set, treat it as allowing
the keyboard to be shown, even when not using touch input.
The slide effect translates all windows as we switch desktop. In a multi
screen setup we don't want windows to enter a different screen during
this animation.
The current code masks everything to the current output. This is broken
for any window that spans across screens even slightly. It will not be
visible during the transform then appear on top at the end.
The new algorithm is, for each screen in each window we crop the painted
area to the intersection of the screen and the screen's translated
position.
ScreenPaintData provides a way to transform the painted screen, e.g.
scale or translate. From API point of view, it's great. It allows
fullscreen effects to transform the workspace in various ways.
On the other hand, such effects end up fighting the default scene
painting algorithm. For example, just have a look at the slide effect!
With fullscreen effects, it's better to leave to them the decision how
the screen should be painted. For example, such approach is taken in
some wayland compositors, e.g. wayfire, and our qtquick effects already
operate in similar fashion.
Given that, strip the ScreenPaintData of all available transforms. The
main motivation behind this change is to improve encapsulation of item
painting code and simplify model-view-projection code in kwin. It will
also make the job of extracting item code for sharing purposes easier.
If a leftmost output is temporarily disabled but outputs on the right
hand side are not moved, some windows may stop being movable because the
Workspace will return bad FullArea. In order to improve handling of
that case, make the FullArea same as the workspace geometry.
At the moment, when an IdleDetector is inhibited, it can emit the
resumed signal. It makes sense on one hand, but also it doesn't.
Inhibited != resumed.
According to the idle-inhibit-v1 protocol specification, we don't
need to emit the resumed signal:
> Likewise, the inhibitor isn't honored if the system was already idled at
> the time the inhibitor was established, although if the system later
> de-idles and re-idles the inhibitor will take effect.
Removing connectors that are still powered leads to a mismatch in atomic
commits: the crtc is still powered, but the connector also still there.
If KWin tries to disable the crtc afterwards, the atomic commits fail because
the connector needs to be disabled at the same time and it's missing from the
atomic commit request.
To fix this, whenever we fail to fetch information or get wrong data from
the kernel (like 0 modes), use the cached information instead and keep the
connector.

These are proper nouns and should be capitalized. And let's consistently
use the term "Virtual Desktop", not just "Desktop" (which can be
confused for the desktop with the wallpaper).
It seems it doesn't bring much and it may backfire. Especially don't
pass GBM_BO_USE_LINEAR as it will limit a lot the buffers that can be
created and GBM_BO_USE_RENDERING use seems to be more harmful than
helpful on most cases.
When the animation slider moved to look and feel a UI was kept within
the compositing KCM that was only visible for non Plasma users so they
still had a way to access this.
This non-plasma version still wrote to kwinrc. In theory this was fine
unless you used both. We also hit an issue where a stray
m_settings->save() call in `reenableGl` would sync the settings to the
wrong place.
This patch moves everything to write to kdeglobals and cleans up any old
entries here.
