Screenshot with partially invisible context menu

SUMMARY
The context menu becomes invisible in wayland sessions on external monitors. One has to hover each entry of the menu to see it again. Seperators keep invisible. See attached screenshot for an example.


STEPS TO REPRODUCE
1. Right click on desktop on an external monitor -> Context menu appears as expected
2. Hover mouse pointer over one of the entries -> All other entries disappear
3. Hover mouse pointer over one of the just disappeared entries -> Entry becomes visible again

OBSERVED RESULT
Context menu becomes invisible

EXPECTED RESULT
Context menu should always be visible

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux
KDE Plasma Version: 5.24.0
KDE Frameworks Version: 5.90.0
Qt Version: 5.15.2
Graphics Platform: Wayland

ADDITIONAL INFORMATION
This happens on external monitors (connected over USB-C) only. The context menu looks perfectly fine on the laptop internal screen.

That's a known Qt bug. It caused by using two monitors with different scale factors.
