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@lists.freedesktop.org
ReportedBy: marlam@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.
