           Summary: on r600 3d applications are rendered too bright
           Product: DRI
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: hramrach at centrum.cz


I am running r600 card with 2.6.34 kernel and Mesa 7.8.2.
 ATI Technologies Inc RV710 [Radeon HD 4350]

Since switching to the card I noticed rendering issues the most prominent being
incorrect colors.

The colors of many objects seem overly bright and lack saturation, the lighted
areas show large patches of white or nearly white color.

The UI which is 2d/unlit looks OK and so do glxgears.

This does not happen on r300 card or Intel card.

I tried running planeshift with software rendering and the character preview
after logging in looked much better. However, after running with software
renderer the issue is gone. This might be because planeshift calculates some
lighting information during runtime and it was changed by the calculations
performed on the software renderer.

Planeshift can be found at http://www.planeshift.it/download.html

I am not sure what the exact issue is. So far I was unable to reproduce it
visibly with a trivial program. However, it also happens when running a 3D
program through wine.
