           Summary: i915: mipmap rendering broken
           Product: Mesa
           Version: CVS
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i915
        AssignedTo: dri-devel@lists.sourceforge.net
        ReportedBy: [EMAIL PROTECTED]


Hi there,

I'm using a recent Mesa GIT version, tag
578641941f45c56deb382317a7ff7cad496679cf, and noticed that the mipmap support
is appearently broken.

I noticed this while playing CS 1.5 through wine. I have gl_texturemode set to
GL_LINEAR_MIPMAP_NEAREST which enables bilinear filterung of the base texture
and mipmaps without filterung (so no trilinear here). Now all textures that
were a few steps away from the player were corrupted, lots of black bars and
stuff. I'm going to upload a screenshot of the problem.

I set the gl_texturemode variable to GL_LINEAR, so no mipmaps this time. And
the problem went away. Of course performance is degraded now and visuals looks
really ugly.
