As of now, we update cursor metadata only when the screen content changes, but
this results into not having smooth cursor movement. We can update only mouse
cursor location when it changes and send an empty buffer with mouse cursor
metadata so clients can have update mouse location.
If the first condition would match (for instance after moving a window),
`windowMove` would be `nullptr`, triggering the crash later.
By the looks of it, it was maybe a typo.

This provides a better fix for the header positioning bug in
the properties list sheet, instead of the previous workaround
(which wasn't enough in some situations)
Upstream bugfix (in the Kirigami component) is not advisable as
it could cause unintended consequencies in other uses/apps

Currently KWin always uses the Options configured in kxkbrc because
QByteArray::constData() is never nullptr. This means that the system
default is ignored completely. Read ResetOldOptions to distinguish
between explicitly setting no options and using the system default.
After recent refactor changes to improve resizing of xdg-toplevel
surfaces with an aspect ratio, the resize effect got really broken. The
resize effect has always been a problem child on wayland.
Unlike X11, geometry updates are performed asynchronously on Wayland.
It's not possible to have a smooth transition after finishing
interactive resize from the resized state to the normal state, geometry
will jump from last moveResizeGeometry() to the current frameGeometry()
and when the client repaints the window, the window size will jump back
to the move resize geometry size. There are no ways to fix that without
contradicting to how the effect is advertised to work, e.g. sending
configure events behind the back. Keeping the frame geometry out of sync
with the xdg_surface window geometry size is also not the option,
geometry updates are already too complex (due to being async).
Another wayland related issue with the resize effect is that the
compositor doesn't know about aspect ratio or any other size
constraints, except min and max size. The client can provide a smaller
buffer to account for various geometry constraints. It will be confusing
to have a mismatch between resize outline and the final real geometry.
Aspect ratio or other geometry constraints won't be exposed to the
compositor, it's a common decision of many wayland devs (including KDE).
To some extent, the wayland issues can be addressed by performing content
updates, with active feedback, the mismatch between outline and the
final geometry would become less severe, but it won't be any different
than resizing without the effect.
Given the wayland issues and in part maintenance costs, this change
drops the resize effect. Note that it can be still reimplemented without
kwin core changes, but it would still suffer from the aforementioned
issues.
BUG: 443434
Currently the plugin needs to set a property in oder to be considered configurable.
In kpackage we have the concept of optional and required files, based on the existence of those
optional files we can define different behavior. For example in Plasma the applets can optionally have a config ui.
Because here we don not use The KPackage:Package class, it is simpler to check the existence of the files on disk.
In KWin we are allowed to break compat and here all first party consumers
have already been ported for quite a while.
Also the querying is very inefficient, because for every plugin where the
X-KDE-ConfigModule property is not defined all available KCMs have to be opened and
their metadata parsed.
This way we also get rid of the deprecation warning for KPluginMetaData::readStringList.
Doe to 1a0031c08a3b41458eb5bf2097b4cd6452ba3d09 we no longer require json metadata to be embedded.
Also we did not use the metadata anywhere, except for finding the correct plugin.
This way we do not need to embed json metadata in the plugins
and can consequently drop the metadata files entirely.
The resulting metadata object might still be invalid, however KCoreAddons
can handle such cases. See https://phabricator.kde.org/T15094 regarding
create better KCoreAddons API for such cases.
Not sure if this was left out on purpose as a kind of deprecation.
It would be necessary to allow port the tabbox switchers to the newer 3.0 API and use their components (such as `Workspace`)
Probably for `Plasma/5.25` now.
It's consistent with m_nextDecoration and m_requestedStates contains
both requested and "not requested" states (i.e. the ones set by kwin
without waiting for acknowledged from the client, e.g. activated).
Running a Plasma Wayland session as root is not insecure, it is in fact the
opposite. There is no way for other users to somehow influence this session
due to the user separation and the user is more likely to only use this for
administrative actions. This is in contrast to regular user sessions, which
most likely start a mix of unprivileged programs next to privileged windows
like some with authorized kauth helpers or even just sudo in a konsole tab.
This change replaces abort() with Q_ASSERT and Q_UNREACHABLE() macros to
make kwin code base consistent. Besides that, Q_UNREACHABLE may
potentially provide the compiler more info that can be used to generate
more efficient machine code.
When moving or resizing a window on X11, the window based screen edges
won't receive pointer input, so handleInteractiveMoveResize() explicitly
pokes the ScreenEdges to check if there's any approached screen edge.
On Wayland, it's not an issue. This change moves X11-specific code to
X11Client to avoid checking screen edges twice.
When finishing interactive resize operation, the move resize geometry is
already good and the client should have sent the corresponding configure
event. So, this moveResize() call is redundant.
This change moves code that is responsible for quitting maximized
horizontally or vertically mode to the start of the interactive resize
operation. It makes handling of MaximizeFull mode consistent, and it
kills one moveResize() call at the end of the interactive resize
operation, which is good because it makes simpler handling of resizing
aspect ratio aware windows on wayland.
However, in order to make resizing of aspect ratio aware windows good
for real, we will need to augment configure events with gravity info.
On Wayland, the move resize geometry and the frame geometry are
completely out of sync.
This change synchronizes emitting of the clientStepUserMovedResized
signal to the move resize geometry changes.
It simplifies code of InternalClient and XdgSurfaceClient, and makes
adding support for other shell surface protocols easier as there's less
boilerplate stuff that you would need to take care of.
With internal clients and xdg-shell clients, geometry updates occur in
asynchronous fashion when interactively resizing the window.
As is, performInteractiveMoveResize() will call resize() if the move
resize geometry is different from the current frame geometry. This can
result in kwin sending excessive configure events.
With this change, kwin will send less configure events during
interactive resize.
It's not practical, regular users don't care about window geometry. One
could argue that it can be useful for creating window rules, but window
rules kcm pulls relevant properties from kwin.
If needed, one can reimplement this feature as a QtQuick script that creates
an overlay window positioned above the window that is being interactively
moved or resized.
Instead of only allowing the current format, send the default tranches modified
to only contain formats and modifiers suitable for scanout.
In order to not fail when we can't do direct scanout with a given format
(because that may require a modeset, which we don't allow), keep a blacklist
of attempted formats and modifiers for the current client.
The fixed size of 1080p makes windows change their size and place. To
prevent that from happening, make the placeholder screen the same size
as the last disconnected screen.
This is not a bullet proof solution, only a fast one. Ideally KWin
should remember the window layout on a given monitor setup and restore
it when reconnected.

This makes the Scene less overloaded and it's needed for things such as
render layers.
In hindsight, it would be great to merge checkGraphicsReset() and
beginFrame(), e.g. make beginFrame() return the status like in QRhi or
VkSwapchain. If it's OUT_OF_DATE or something, reinitialize the
compositor.
Same as real hardware wl_keyboard, key should be sent before modifier
change. For example, Left Ctrl press and release should produce
key events in the order of Control_L and Control+Control_L.
When creating the texture containing the window decorations, the drawing
code now directly handles the rotation for the left and right
decoration, instead of rotating the image after it has been drawn.
The padding, to prevent texture bleeding, is now a fixed value instead
of being scaled. With this change, there are no longer visual artifacts
for window decorations with rounded corners, when the scaling value is
fractional.
On X11, if buffer age is unsupported, kwin can do some quirks like
copying parts of the front buffer to back buffer to avoid repainting the
whole screen.
Currently, the copying is performed in the opengl scene, which is not
perfect because it makes the scene responsible not only for painting the
scene but also some low level platform specific shenanigans.
This change moves the copying step to the glx and egl backends. It
simplifies the opengl scene, makes it less overloaded and more open to
changes, but it also duplicates code, which is not ideal. However, given
the de-facto deprecated state of the X11 platform, it's sort of acceptable
as the main focus is now on wayland session and the things that are
needed to make it fly as expected.
