I still can't find a scenario which reliably reproduces this gpu hangs. I only
know that they happen sometimes but apparently they are unrelated to a specific
activity.

Sometimes they appear when I close a 3d game (namely X3:Reunion) but in other
situations they just appear when I scroll a webpage (without Videos or 3d
Stuff).

Interestingly enough, the gpu hangs don't seem to appear right after boot but
that could be a coincidence.

The only thing that seems to happen most of the time is that if it has hung
once it will hang again shortly after (2-3 Seconds inbetween) a few times until
I've managed to close whatever GPU accelerated application is running (chrome,
steam, ...)

If you have any pointers on what I could try to find a scenario to reproduce
this bug please tell me.

WebGL didn't help and rapidly opening and closing steam games also wasn't very
useful.
