            Bug ID: 97285
           Summary: Darkness in Dota 2 after Patch "Make Gallium's
                    BlitFramebuffer follow the GL 4.4 sRGB rules"
           Product: Mesa
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Mesa core
          Assignee: mesa-dev at lists.freedesktop.org
          Reporter: edmondo at eriadon.com

After updating to mesa master (6575ebdc), Dota 2 colors are much more darker.

>From the IRC log 2016-08-10 it seems haagch already bisected it:

15:53 #radeon: < haagch> anyway, am I the only one seeing some opengl games
being far too dark, like dota 2 and portal 2? 
16:03 #radeon: < nha> haagch, since when? maybe since those sRGB changes? 
16:38 #radeon: < haagch> nha: you were right,
3190c7ee9727161d627f107c2e7f8ec3a11941c1 is the first bad commit 

I can confirm that reverting patch 3190c7ee9727161d627f107c2e7f8ec3a11941c1
takes away the darkness in Dota 2.

My configuration:
OpenGL renderer string: Gallium 0.4 on AMD CYPRESS (DRM 2.46.0 / 4.8.0-rc1,
LLVM 3.8.1)
OpenGL core profile version string: 4.1 (Core Profile) Mesa 12.1.0-devel
(git-796d760)
OpenGL core profile shading language version string: 4.10
