--- Comment #2 from Leonard Lausen <leon...@lausen.nl> ---
Thank you Nate for taking a look. I think the behavior has improved as of
Plasma 5.21. The session/plasmashell does not crash anymore when removing the
screen containing the system try. However, the multi-screen behavior is not
completely stable yet either.
I observed two issues (please let me know if you'd rather have a new
bug-report).
Further, in the first message I forgot to include that the main screen (laptop
screen) of the setup is a 4K screen and scaled, whereas the external screen is
a FHD screen and not scaled.
Issue 1: plasmashell can trigger qt5-wayland crash when moving the system tray
between screens:
Application: Plasma (plasmashell), signal: Aborted
