--- Comment #85 from Henning Fleddermann SickThought@gmx.net 2008-08-23 05:53:39 --- I tried fglrx 8.8 yesterday and the bug is not fixed.
Also I've got some additions/corrections to my previous comments: I was wrong about the performance being ok. It looked like that because my cpu seems to be beefy enough to render WC3 in software mode. But more demanding games (WoW eg.) are very slow or crash (Max Payne 2). Also ulimit -s unlimited does not fix the bug for me, not with fglrx and neither with radeon.
What puzzles me is that this bug happens with fglrx _and_ radeon (with Mesa from git). It really seems to be more of a wine bug that a driver bug. Comment #64 seems to make sense.
