--- Comment #3 from Roderick Colenbrander thunderbird2k@gmx.net 2007-10-28 10:36:01 --- One remark this bug wasn't the ati multithreading bug. I spoke the user on irc. Not just d3d apps crashed but also opengl apps on wine. This was using fglrx 8.42.3, the use of the xorg option UseFastTls=2 fixed it.
