Issue:
2 programs I use are Nethack-qt and OSM Scout Server, installed via yay & flatpak, respectively. Yesterday, when I closed OSM Scout Server, the program itself closed, but the window stuck to the screen. KSysGuard showed no sign of the program either. I didn’t try to reproduce it, but left it for next weekend. Today, I was playing Nethack-qt and it showed the same behaviour.
Observed behaviour:
Cannot remove this zombie window shadow without killing Xorg. It doesn’t appear on other virtual desktops though.
Expected behaviour:
The window shouldn’t exist like this in the first place 
It should be gone after showing me my result
What I’ve tried:
kquitapp5 plasmashell && kstart5 plasmashell- kill Xorg (only workaround atm, though it kills my other apps)
- searched google, but nothing remotely related to this issue
How do I get rid of this zombie window? And how do I prevent this from occurring in the future?
