           Summary: [r300g] No texture shadow in ogre3d
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: sh@lutzhaase.com


Using r300g, I'm unable to get texture shadows using the ogre3d graphics
engine. Mesa texture shadow demos work fine. In fact, in the ogre3d texture
shadow showcase demo I can see a very distorted texture shadow on the side of
the base plane. In my own scenes, I get no shadows at all. Stencil shadows work
just fine.

In order to pin down the problem, I ran a few tests. As it turns out, the
problem really only exists in r300g (as far as I could test). It works fine in
r600g and gallium3d llvmpipe. For reference, it also works in the NVIDIA and
AMD proprietary drivers.

I also reported the problem in the ogre3d forums
(http://www.ogre3d.org/forums/viewtopic.php?f=4&t=64781) but it appears to be
the wrong audience to post this issue in. 

Due to the abstract nature of ogre3d, it is hard for me to create a minimal
case without ogre3d.
