--- Comment #20 from Tobias Jakobi liquid.acid@gmx.net 2008-10-13 16:40:58 --- It looks like this bug is now only apparent if ORM is set to backbuffer (I didn't try pbuffer though).
It's not there with FBO, even with wine-1.1.5 - it's also gone there.
So the problems stays with backbuffer mode. Maybe someone wants to also check this with pbuffers.
