Summary: GL_EXT_texture_sRGB (included in OpenGL 2.1) is broken Product: Mesa Version: 7.10 Platform: All OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: marlam@marlam.de
The GL extension GL_EXT_texture_sRGB (which is in OpenGL 2.1 core) 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; the textures are sampled as if they were normal GL_RGB textures. This results in wrong colors (e.g. in the Bino 3D video player: far too bright).
I'm running Ubuntu 11.04 on x86_64 and get the following version info from GL: OpenGL version: 2.1 Mesa 7.10.2 OpenGL renderer: Gallium 0.4 on AMD RV710 OpenGL vendor: X.Org
If you need more information, please let me know.
[This is the same as bug 32323, but re-reported for newer Mesa versions]
