Welcome to the forums!
This looks like a mipmapping issue, and so I strongly suspect that it is due to a bug in Panda that only occurs when using a very old OpenGL version. This bug was incidentally just fixed yesterday.
Please try and see if today’s development build fixes the issue:
panda3d.org/download.php?pl … =devel&sdk
Out of curiosity, though, I would like to know more about your graphics card. It could be that you do not have up-to-date graphics drivers installed, which could prevent you from accessing many useful graphics technology. Adding a line with “notify-level-glgsg debug” to your etc\Config.prc file will make Panda print out information about the supported OpenGL version and extensions.
