I can confirm the font corruption issue too, using Compiz, Nvidia 195.xx drivers, no twinview, and subpixel smoothing. The font corruption is serious enough to render OpenOffice almost unuseable. Changing to "Best Shapes" does correct the problem but it isn't an intuitive fix, and makes a very bad first impression to new users of Ubuntu.
