--- Comment #3 from Tobias Jakobi liquid.acid@gmx.net 2008-08-01 06:21:14 --- Wine settings: ORM=backbuffer GLSL=disabled
Ingame settings: res=1024x768-32 PPE=medium PSS=off (*) mirrors=off CEM=on (**)
(*) pixel shader skins (**) cube environment maps
Switching CEM off makes the windows transparent again, so the problem seems to be there. Attaching screenshots in a minute.
