For me this issue arose in Ubuntu 12.10 and still happening in version 13.04. This is a terrible bug and makes Ubuntu and LibreOffice almost unusable for me!!
Fortunately, I found a work around: 1. Open NVIDIA X Server Settings, select Antialising Settings on left panel; 2. Turn ON "Antialising Settings->Override application settings" and move the slider to Off position. 3. Turn ON "Anisotropic Filtering->Override application settings" and move the slider to 1x position. 4. Close NVIDIA X Server Settings I did some tests and, so far, the bug did not happen.
