Created attachment 36709 [details] +xvidmode log
Still a problem in wine-1.3.29-169-gdb882bf.
Nvidia 250 / driver 280.13
it already rejects some gamma ramps... is that log including gameplay? what happens if you switch to a console and run xgamma (you might need to set the display to :0 ) i bet it's "-> Red 1.000, Green 1.000, Blue 1.000" and so is not a gamma problem, so i most likely can't help (and setting another gamma value via xgamma also won't help)
