           Summary: R600 misrenders irrlicht demo (01helloworld)
           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: curaga@operamail.com

Software renderer (correct output)

The R600 driver misrenders the first demo of Irrlicht
(irrlicht.sourceforge.net) when edited to use OpenGL instead of irrlicht's
software renderer.

The demo loads an animated md2 model with a bmp texture.


Tested on Mesa 7.8.2 and 7.9, r600 fails on both, software renderer works on
both. Screenshots attached.

HW: Radeon HD4350

This is still there with Irrlicht 1.7.2.

On the Irrlicht forums it was pointed out this model uses a NPOT texture, and
indeed scaling it to powers-of-two makes r600 render it correctly.

Please test with r600g, we don't actively support r600c.
