Description systeminterrupt 2020-12-09 19:45:42 UTC 
SUMMARY
I started "Zoom" (the video conferencing software) on KDE Plasma/Wayland and it opened up with a window showing the "connecting" message. Normally this window disappears when it ends up connecting me to the meeting.

However, today this window did not go away at all --even after I shut Zoom down. There is no PID for Zoom and no window in the KDE panel either. Ksysguard "kill window" function does not detect it either. Placing other windows over it does not erase it either which confirms that this is not an "unrefreshed" region of the screen.

I am not sure the steps to reproduce will be of much help as this just happened once.
