Application::processStartupEnvironment() returned
QProcessEnvironment::systemEnvironment() which means the current
environment of KWin when this function was called. By setting
InheritFromParent we can replicate this behavior.
This fixes KWin starting processes on X11.
The events we forward to the offscreen QML view are with our own
QPointingDevice instance, which has a devicetype of touch but a null pointerType.
In Qt5 this was enough, but pointerhandlers in qt6 refuse events with an undefined
pointertype, so we have to explicitly set it to finger
BUG:473541
If a transaction entry is removed, the graphics buffer reference will
be dropped and it's possible that the TransactionDmaBufLocker is going
to be destroyed as well.
If that happens, the transaction may remain in the locked state.
At the moment transactions from the same client are applied in the
commit order even if the trasactions affect unrelated surfaces.
This patch desynchronizes transactions affecting unrelated surfaces.
With this, if a client updates two surfaces (as an example, Firefox with
two windows) and one of its surfaces takes longer to render, the other
surface is not going to be slowed down.
Another nice thing is that it removes client from Transaction, which
might be potentially useful to the Workspace for coordinated resize or
something.
This makes unconstraining code more reusable (in case of applet popups
use xdg-positioner too), and in general, it makes sense for better
encapsulation.
Transactions provide a way to apply new surface state to multiple
surfaces atomically.
A transaction can be locked. In which case, it's not going to be applied
until all locks are dropped. For example, this can be used to delay
applying new surface state until the committed buffers become idle.
After introducing SurfaceExtension, SurfaceRole has lost its commit()
function. It serves informative purpose now only.
Shell surface implementations don't have to inherit from SurfaceRole.
By making SurfaceRole act more like a value type, it's possible to fix
role handling in wl_pointer.set_cursor.
There's "major" and "minor" defines that can get implicitly included, for
example with musl libc. To prevent that from breaking compilation, rename
the methods
Since there is now exist the signal right before maximize, use it to
set oldGeometry instead of storing previous values every time with
windowFrameGeometryChanged.
This fixes the effect under Wayland.
In many cases it's irrelevant, what we care about is whether given effect
is loaded and performs its function. So remove these paranoid checks
except the tests where it's important to use OpenGL compositing.
