Otherwise, if render time prediction and actual render time are very different,
a lot of frames get dropped and in some cases more frames than is useful are
rendered, creating stutter instead of only unnecessary latency
BUG: 487605
A bad rebase in commit 43e5f17547 inadvertedly
reverted half of the fix from 1f1c54ca6c. As a
result, custom tiling would appear broken again for keyboard layouts where caps
lock is achieved by pressing both shift keys at the same time. Reapply the half
of the fix that went missing.
When a new mouse event is made it updates the global position of that
device. This causes issues if a mouse event is forwarded with an
adjusted position then used afterwards.
`QPointingDevice::primaryPointingDevice` creates a new pointer device
internally if the seat name does not exist. It is then shared between
future usages.

This improves the integration of the XcursorTheme class with the rest of
the Qt ecosystem, for example it should be possible to load cursor themes
from Qt resources.
When rendering a frame takes longer than a refresh period, allow rendering to
happen before the previous frame is presented. This way the effective refresh
rate is increased, without increasing latency or impacting frame pacing more
than necessary
Plasma::Dialog contains logic that we don't want for a kwin window and
is considered deprecated. Dialog uses the width of the main item which
results in an unavoidable binding loop.
PlasmaWindow allows us to propagate implicit sizes upwards correctly.

kglobalacceld needs to process all key events to detect whether
a modifier only shortcut has been triggered.
On the other hand, when using Meta+Space keyboard layout switching
shortcut, we will get the following key syms (not native scan codes)
- press meta: Meta_L
- press spacebar: Super_L
- release meta: Meta_L
- release spacebar: Space
The fact that xkb reports Super_L when the spacebar is pressed trips
modifier only shortcut detection in kglobalacceld, and it's likely
that kickoff will open after pressing Meta+Space to switch the keyboard
layout.
In order to prevent that, kglobalacceld needs to see all key events
even with invalid key codes. As an alternative, we could explore the
possibility of using native scan codes instead of mapping keysyms to
key codes, but that needs thorough analysis, which we have no time
for.
The check was introduced in 4403e86acc.
After that check is removed, the test still passes.
This is the backend that will be used by the portal to enable
the functionality of the input capture portal.
When the cursor tries to move out of the workarea across a barrier
that the portal registered all input events are filtered out
and forwarded via eis.
The cube effect has a placeholder which can update the delegate at
runtime. There's an "add desktop" button which then might give us 3
virtual desktops. As a general rule any setter exposed via a declarative
API should always perform the setting.
Reloading has to be delayed because otherwise we unload the caller.

With this change the preferred buffer scale, transform and color
description properties will be latched to xdg shell configure events.
This should ensure that the clients are told the preferred buffer
scale before the first configure events.
This makes it a bit more conservative for reducing latency, which decreases the
amount of dropped frames in desktop usage a lot (by 13x on my desktop, 2x on my laptop)
pointerEvents contain all motion events, the xwayland filter is only
concerned with forwarding clicks. Right now we would update an invalid
button state constantly. It did nothing harmful but was still a bit
silly.
An EDID can contain zero or more detailed timing definitions, which can contain
more precise physical dimensions of the screen (in millimeters, as opposed to
centimeters).
The Xorg server has similar logic for determining the physical screen size from
the EDID: pick the first sane size from the detailed timing definitions, and
fall back to the screen size given in the "Basic Display Parameters & Features"
section.
BUG: 486585
Apparently people have differing ideas of what "vertically" and
"horizontally" mean, and some feel that this wording contradicts the
icon.
That's not accurate, but the wording is admittedly a little a bit
ambiguous. We can clarify this by using super duper explicit
terminology that always matches the icon.
