Avatar Head Error

[Plymouth]

So there seems to be a few different problems. I turned off the Stereo setting in NVidia's settings and that stops nearly all the problems. The head no longer slides and the no heads cause crashes. But the problem still remains that all the male heads are displaying as too small. So I'm wondering what might be behind the head-size problem. And if you have any idea what I might be able to do to fix the stereo problem let me know. I'm fairly sure all the drivers are current, but I'll check that again and make sure the settings are all correct.
