I noticed that the compositor backend renderer was set to OpenGL3.1. Setting is to OpenGL2 seems to solve the issue for now. Will test some more and come back to update.

Since then, I'm having graphical issues. It looks as if the screen is not refreshed when needed. Examples: - clicking a link in a browser - typing commands in Konsole - typing this bug report When I force a "big" screen update, for instance by alt-tabbing (usually, pressing only alt is enough) the screen is refreshed. When a "freeze" happens, the mouse cursor can still be moved. I have an HP laptop using the Intel i915 driver. However, there is also an Nvidia gpu on board, which might muddy the water a bit. However, the nvidia gpu should be switched off (prime-select query returns intel). There are no options set for the i915 module. Additionally, it seems that the issue doe not occur on a fresh boot, only after a sleep or hibernate.
