--- Comment #59 from Artem S. Tashkinov t.artem@mailcity.com 2009-11-15 14:56:11 --- The only relevant SRGB that I found (http://source.winehq.org/git/wine.git/?a=search&h=HEAD&st=commit&...) was this one:
http://source.winehq.org/git/wine.git?a=commitdiff;h=33ca3c02076082131c0b846...
That means that this version of Wine: http://source.winehq.org/git/wine.git?a=tree;h=82322e025dafc9a190d11a52a6130... should work just fine or this bug has never been fixed in the first place.
If the aforementioned Wine version indeed works (please, someone test it) then we need to find out what Wine git commit has broken the Source Engine.
However I can be all wrong, and the right SRGB fix was another one.
