--- Comment #10 from Christoph Haag <haagch.christoph at googlemail.com> ---
Sorry for first only answering for Sanctum2, in Antichamber it often takes a
long time to reach the point where it happens.

Sanctum2 starts and runs okay now I guess. But there are pretty big problems
with it and I have no idea whether they are caused by this here or not:

As soon as the fullscreen window with Sanctum2 isn't displayed anymore (e.g.
minimizing or switching workspaces), the whole X display is getting scrambled,
but restores immediately when displaying the game window again. (Could of
course be just the PRIME setup).

I started setting the graphics options higher and higher and at some point, got
a GPU lockup. No gpu faults like in upvoid, just a lock up I think (blocked and
resetted and stuff). I got a complete machine lockup moments later and didn't
get more information. Again, no idea if it's related.

But the register spilling implementation at least works and seems to not cause
any direct problems.
