Public bug reported:
Hi DevTeam,
Just came across a weird bug - got logged off forcefully the moment I
connected my External Monitor via HDMI.
Happened twice in the last 30-40 minutes, hope the Logs provide enough
info to identify what went wrong.
In the last few days I also noticed that the Login Screen crashes a few
times on cold boot - before I can log in.
Thank you,
Bogdan
