Subject: [PATCH] xdgshell: Tell the compositor the screen we're expecting to
|
|
|
c54cd9 |
fill
|
|
|
c54cd9 |
|
|
|
c54cd9 |
The xdgshell protocol allows us to tell the output to fill. This makes
|
|
|
c54cd9 |
it possible to use fullscreen confidently on systems with multiple
|
|
|
c54cd9 |
screens knowing that our windows won't be overlapping one another by
|
|
|
c54cd9 |
calling setScreen accordingly before QWindow::showFullScreen.

Pick-to: 6.1 6.0 5.15
