Additional note regarding compositing:
*) The problem happens regardless if compositing is enabled or disabled. *) Enabling compositing fixes the problem (as far as I can tell always).
If I start with compositing on, I need to toggle it for the problem to be gone. If I start with compositing off, I just need to enable it.
--> Something that is done when compositing is turned on fixes the problem.
(I use KDE and use Shift+Alt+F12 to enable/disable compositing)
