           Summary: r300g produces black textures in nexuiz with glsl
                    offsetmapping on
           Product: DRI
           Version: XOrg CVS
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: kontrollator at gmx.de


When i run stock phoronix test suite nexuiz i get black textures. I found that
this is caused by using th effects-high.cfg. when i swith to effects-normal all
textures look as they should. i found that this is caused by glsl_offsetmapping
set to 1 (aka enabled). when i change it to 0 everything is okay, when i change
it to 1 all textures are black. System is an rv410 (x700 mobility), latest mesa
/ drm / kernel from git as of today. i filed this bug against  drm, if it is
more likely a mesa problem feel free to reassign it. if you need more info
please tell me. thank you for your time.

greetings jan kreuzer
