In both Tomb Raider and Deus Ex Human Revolutions a large area is missing. The edges are moving an shifting around a little.
I'm using Ubuntu 13.04 (but the same problem was present on 12.10), ati hd 7770 with the fglrx-update drivers.
In Deus Ex the area is white but at the same position.
Can someone help me figure out whats the problem?
