That sadly looks vaguely familiar... I think its the point where I gave up chasing bugs last year, because I was going soft in the head staring at this stuff for several months non-stop.
It taking several hours to reproduce didn't help.
I suspect its something iffy with the Intel driver, because I could never trigger it on AMD, but of course, no guarantees ...
I'll try and find some time again to chase this down once Alexander sorts that AUX issue.
