I am using a Radon HD6850 and just bought the indi bundle. Torchlight is missing all face textures (and face textures only). I have had problems with shaders before (graphic would be displayed as black), but what I am seeing now is a simple removal of the texture, I can see through the head. The fps is fine on full graphics so it doesn't seem to be too much of a driver issue (I am using the drivers that came with ubuntu). I downloaded the game through the USC. Has anyone had this issue and managed to fix it?
Running Ubuntu 12.04 LTS
It's not coming from your computer, everybody playing Torchlight for Linux is experiencing the same bug. The best you can do is wait a few days until a new build is released which will hopefully fix this issue.
