SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***

Only my second bug report please let me know if I am missing any info.

STEPS TO REPRODUCE
1. Have 2 monitors, external monitor is 1920x1080 no scaling native monitor is 2256x1504 @ 150% scaling
2. Right click on background
3. Navigate to submenu

OBSERVED RESULT
After navigating to sub-menu the main context menu disappears and starts experiencing flickering and other graphical issues (video attached). I had a similar issue on 5.26 where parts of the menu would disappear but the flickering is new.

EXPECTED RESULT
A stable context menu with no graphical glitches.

Hopefully should all be resolved by Plasma 6.

Sounds good. Out of curiosity, do you know why it's flashing/strobing more on 5.27 than on 5.26? Is there something that's refreshing the desktop or menu?
