In Ubuntu 12.04, the path is actually

The solution seems to be to use Mesa instead of the regular drivers. In Ubuntu 11.04: Install libgl1-mesa-dev , then preload /usr/lib/mesa/libGL.so when starting Blender. On the command line: LD_PRELOAD=/usr/lib/mesa/libGL.so gdb blender In QTCreator: Projects mode > Run settings > Run Environment >...

A bit more testing: this happens even if using plain old gdb instead of QTCreator, and it happens whether or not Compiz is running.

Matrix inconsistencies

Hi! I'm having trouble with a script I'm writing. I think I've found a bug in Blender, but I thought I'd ask here first. The script multiplies two transformation matrices together and applies them to an object. In the 3D view this works fine, but when the scene is rendered the object has a different...
