Weird red/black texture artifact and normals problem

I’m running Panda 1.7.2 on Ubuntu 10.10, x64, and I’m experiencing this weird visual artifact. In many scenes everything is overlaid with an odd red/black texture, and a kind of faceting that looks like something’s terribly wrong with the normals. Really strange… [/img]

Can you give more information? Like what kind of video card you use, which GPU drivers you use, the output of glxinfo, some screenshots?

Sure - here’s a screenshot of Ralph with something funny happening to his textures.

Card: Geforce GT 330M
Driver version: 260.19.06

OpenGL info (from glxinfo):

OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce GT 330M/PCI/SSE2
OpenGL version string: 3.3.0 NVIDIA 260.19.06
OpenGL shading language version string: 3.30 NVIDIA via Cg compiler

I think this is a problem specific to this one insall, not a panda issue. I’ve installed the exact same build on a few other machines including one with identical hardware, and everything works fine … just thought I’d see if anyone might have stumbled on something like this before.
