--- Comment #71 from Roland Baudin roland65@free.fr --- Hi, not sure but I suspect a problem with the color profiles. Do you have a color profile installed for your monitor? I have such and it makes perhaps a difference.
You can use dispcalGUI to install a color profile or you can simply use the sRBG profile provided on Windows and copy it with:
cp "sRGB Color Space Profile.icm" ~/.wine/drive_c/windows/system32/spool/drivers/color
This is perhaps the same issue encountered by tom@fullcircle.de on an INTEL card. I'll do some testing this week end to see if I can reproduce your issue on a fresh install without color profile.
