           Summary: [r300g] lightmap texture corruption in ut2004
           Product: Mesa
           Version: git
          Platform: x86 (IA32)
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: aaalmosss@gmail.com


Certain lightmap textures are corrupted when viewed from certain angles in
ut2004. As the attached screenshot shows, only the lightmap gets corrupted.

Bug 28800 may be related.

I have an rv350 and libtxc_dxtn.so is installed.

I renamed it, because I found that not just ut2004 shows these symptoms. Other
games are: nexuiz (mostly on the weapon and other players), sauerbraten (on the
weapon), doom3 (on nearly all surfaces), et:qw (on most surfaces).

Sadly, the patch has no apparent effect.

I tried to change the texture detail and to turn detail textures on and off in
ut2004, but the always same surfaces get corrupted. In the menu of doom3 the
mars is corrupted only if bump mapping is not enabled (I'm not entirely sure,
but it seems to me that only the clouds get corrupted).
