--- Comment #30 from Thomas Sisson <thomas.sisson.1 at gmail.com> ---
I know this bug is closed, but I think there is an issue with some of the free
graphics drivers provided by some packages from some Linux distributions. I'm
having this same issue today with Ubuntu 12.04 LTS with KDE 4.8.5. (a reinstall
from 13.04 Beta) Once I install Catalyst Control Center for the AMD/ATI
graphics to install the proprietary driver, the problem should go away as it
did before.

I believe the current fix is to default to Xrender if there is a graphics
issue, but a reinstall or upgrade may leave a user with KDE settings in the
home folder that are based on having a better driver that is missing after an
upgrade or reinstall if the home folder is not touched during installation.
