My monitor is a three monitor system with the main monitor (central) on DP and
the two others on HDMI with DP adapter. Until recently that worked fine,
workspace is "connected" thus the mouse pointer flows from on to the other
monitor. 
I am opening in this condition one single user: no problem, not even when using
FF. 
I am opening (with the first user open and using firefox) a new users session
via "switch user", the news session will now go down with flicker and crashes
(as the attachment posted). 
When I am loging out completely the first user and only then I open the other
user, no problem too, works as expected. 
I am having currently:entropy@silversurfer:~> uname -a
Linux silversurfer.fritz.box 6.8.9-1-default #1 SMP PREEMPT_DYNAMIC Fri May 10
08:51:14 UTC 2024 (d3445e0) x86_64 x86_64 x86_64 GNU/Linux

I can try to go back to 6.8.8 (where I had no issues afaik). 
However for tasks I have to do tonight I can do this only very late or
tomorrow, so you will have the answer on your 6.8.8 question tomorrow. 
Hope that helps. 

(Thought about to rename the bug in highlander problem, (since there can be
only one ;-) ) SCNR
