MS teams makes the whole GUI stall: GpuWatchdog segfault

Since I use microsoft teams on my Debian buster machine, I get a GUI freeze sometimes: The mouse pointer can still be moved on the screen, but no visible feedback on clicks or keyboard presses. Also no switching to a console with ctrlaltF1 I could not help myself other then sshing to the machine to restart Xorg. The dmesg shows me fingerprints of teams, but I guess the deeper problem must the in the nouveau GPU driver?
