           Summary: Problem with Blender and big textures
           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 at lists.freedesktop.org
        ReportedBy: disnel at disnel.com


When I try to use a big texture (4096x4096) in blender 2.56beta, I get
following error:

r300: CS space validation failed. (not enough memory?) Skipping rendering.

and no texture is displayed. Smaller textures (tested 2048x2048) works fine.
Also with LIBGL_ALWAYS_SOFTWARE=1 it works fine. When I try bigger texture
(8000x6048), I get no error, but also no texture and I can see screen
corruption with Compiz (bad window shadows, applets on panel, background on 2nd
display etc).

Blender files with textures and image with corrupted display are here

(I dont'know, how big files can I attach here). I'am using mesa
7.11.0-git2011016+gallium from xorg-edgers with Ubuntu 10.10 x86_64. My
graphics card is Radeon X1400.
