--- Comment #9 from Tobias Jakobi liquid.acid@gmx.net 2008-10-13 16:44:00 --- Currently taking a (new) look at it.
It still happens with wine-1.1.6 (reconfirming there).
However Alexander was right. It doesn't depend on NP2 settings, but on GLSL settings (and ORM, but since backbuffer isn't usuable for me I have to stay with FBO here).
So ORM=FBO for all checks done here. Post processing effects are set to medium.
Enabling GLSL does indeed fix the issues (not the GL errors though). However the PP effects now render fine again. Disable GLSL and everything breaks.
I'm going to do a new bisect in the next few days.
