SUMMARY
Using Wayland on Arch Linux, when getting an app to fullscreen. 
Using multimonitor setup with different scaling applied to different monitors (fullhd 125%, ultrahd 175%, fullhd 125%), so that might be one of the needed requirements.
Doing so fills journalctl with priority 3 messages like:

Thank you for the bug report, I'm sorry we weren't able to get to it yet. I'm not able to reproduce any errors in kwin_core when making a window fullscreen.

If this issue is still reproducible in either Plasma 5.27 or Plasma 6.2.5 (the latest released version), feel free to re-open this bug report.

Thanks for understanding!
