screenshot of bug

As mentioned in bug 35434 there is a glitch in the game ETQW where the screen
just renders garbage. It doesn't seem to be related to any settings in the game
and is only reproducible on some places in some of the maps.

The best description to reproduce the bug is the one given in bug 35434:
"I know now exactly where this is reproductible. For example, in "area
22" map, start with Strogg (soldier), you will land on the right of the Strogg
base, then just turn left (looking to the Cyclope), and there is artefact (or
now freeze&shake). I noted that watching the Cyclope on this map always results
in this behavior."

I have also provided an apitrace which makes it easy to reproduce the problem:
