           Summary: GL_EXT_texture_sRGB is broken
           Product: Mesa
           Version: 7.9
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/R600
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: marlam at marlam.de


The GL extension GL_EXT_texture_sRGB defines the texture formats GL_SRGB and
friends and specifies that sampling such a texture automatically converts the
values from non-linear RGB (sRGB) to linear RGB.

However, this conversion is not performed on my system; the textures seem to be
sampled as if they were normal GL_RGB textures. This results in wrong colors
(e.g. in the git version of the Bino 3D video player: far too bright).

I'm running Ubuntu 10.10 on x86_64 and get the following version info from GL:

OpenGL version: 2.1 Mesa 7.9-devel
OpenGL renderer: Mesa DRI R600 (RV710 954F) 20090101 TCL DRI2
OpenGL vendor: Advanced Micro Devices, Inc.

If you need more information, please let me know.
