"My guess is there is a bug in the video driver that shows when the 3d section of the video card is used."
Yup, you are 100% correct there. I've forgotten about this bug - until you commented & I got the notification about it. I suffered from similar problem to you. But I managed to resolve it by installing the xorg-edgers PPA : https://launchpad.net/~xorg-edgers You might wish to try the driver first : https://launchpad.net/~xorg- edgers/+archive/drivers-only (I went for the whole setup though - Acer laptop here with Intel i915 chip) Another safer bet compared to the whole xorg-edgers is probably the Ubuntu-X PPA : https://launchpad.net/~ubuntu-x-swat/+archive/x-updates Hope it helps someone else.
