Notes:
- My screens are stacked. The upper one runs at 60 Hz and the lower at 75 Hz.
Making both of them run at 60 Hz makes no difference.
- The GUI doesn't seem to crash. Pressing the Super key opens the App Menu, but
since the screen content is corrupted, it cannot be read.
- Workaround: switching to the SDDM TTY (Ctrl+Alt+F1) and then returning to the
GUI (tty2).
