The way the glide effect works is that it takes 2D geometry and applies
the perspective projection to it on the CPU side. The reason we do it is
that the scene is 2D.
However, this leaves us with the well known problem where a texture
that's mapped to a trapezoid won't be correctly interpolated along the
diagonal.
It can addressed by performing a perspective division in the fragment
shader, but given the way the effect is structured, it's off the table. So
instead subdivide the window grid.
BUG: 488840
We are doing half a job of resetting spa_meta_cursor, the actual cursor
content is still left as is. On the other hand, it should plenty enough
to simply reset the cursor id. The clients are expected to call
spa_meta_cursor_is_valid().
currentTemperature, targetTemperature, and mode properties have "u" type.
But there is a mismatch between the property types declared in the
Q_PROPERTY macro and the org.freedesktop.DBus.Properties.PropertiesChanged
signal.
This change makes the property types consistent and match the types
declared in the xml file.
Amends a136a159f9 which changed the value in the kcfg file that the kcm reads, KWin uses options.kcfg
4f322e24d3 changed the in code default but this will be later overriden when loading the options.
Adds support for BGR888 and RGB888.
Some clients use it and we just fail to render them, making devs
thinking that kwin is broken.

KWin already supports following org.freedesktop.locale1 for the
keyboard keymap, but only by passing a command-line option. This is
typically used in SDDM when running the greeter in kwin_wayland.
We want to use locale1 mode in livesys environments too, so that
environment-agnostic installers can configure the keyboard and also
immediatly apply the same configuration to the running desktop.
When KWin is started through `startplasma` we cannot easily supply
an extra command-line option, so we need to make this configurable
from the external environment, in the form of a KConfig.
The command-line option will keep precedence over the KConfig.
In case the current state and the pending state have the same buffer for
a particular side or a corner, that buffer can be prematurely released
because the buffer in the current state is unreferenced first.
The ref/unref order should be vice versa to ensure that the GraphicsBuffer
is not released prematurely.
This effects is off by default, which means to instruct someone how to
use it for debugging purposes, you need to both tell them to enable it,
and then also teach them how to assign a shortcut for it.
Since it's off by default, there's no harm in setting a shortcut, which
simplifies the enablement instructions. I've chosen Meta+Ctrl+Alt+P,
which uses so many modifiers that it won't conflict with anything.
This allows us to make the code that computes transition timings more
cleaner, and other time constants are in milliseconds, so it makes sense
to make m_transitionDuration store milliseconds too.
The current code is unreadable:
- it creates a lambda that captures two local variables for latitude and longitude
- then it copies values from the config to those local variables
- calls the lambda
- and finally copies the data from the local variables to the NightLightManager fields
That code can be simplified by simply calling checkLocation() directly
and using an if statement.
Morning and evening timings should be ordered correctly. When computing
the daylight duration, that ternary operator should not be needed and it
hides other bugs.
There are a couple of reasons why it's worth removing it:
- it's error prone. If one forgets to pass correct "force" flag, night
light will break
- it contributes some complexity
- updateTransitionTimings() is not called in any hot path and the code
that calculates the position of the Sun is not resource intensive
