Hi Jordan,

welcome to OSS and Plasma.

yes sure, that's bug 360719

No, that is not enough for a SoK project. Once the issue is identified, 
it would be fixable in hours max a few days.

If you want to hack on that issue I can provide you pointers where to 
look into the code.

It seems to be only a problem with Compositing enabled, so one idea to 
start would be in the kwin/useractions.cpp to verify that all windows 
get closed. Then as a next step to verify that the Unmanaged for the 
menus get recognized as closed. If both would be the case the next 
interesting aspect would be to figure out why it's not removed from 
rendering. Thus getting closer to the problem.

The description of the problem here gave me an idea which allowed me to 
reproduce the issue, so kudos to that!

Welcome on board!
