The flag that was removed with the patch in the link here: http://source.winehq.org/git/wine.git/?a=blobdiff;f=dlls/wined3d/directx.c;h... caused the game "Sins of a solar empire" to not startup anymore.
This is not the right way to fix it. The code is quite new but works very differently from the old code. What videocard are you using? At what color depth? What offscreen rendering method are you using? Further could you provide your glxinfo output?
