To reproduce: - Boot a Quantal live system or a fresh installation - Start software-center. - Move the mouse in its window or click anything. Result: Text and some graphics become massively corrupted (See also attached screenshots and short demo video). I have seen this kind of corruption so far in software-center, ubiquity- slideshow (during installation) and one time on filename text field of gtk-filechooser. Booting the system with "nomodeset" seems to make the problem go away, as well as installing the propritary Nvidia drivers.
