Hitting the web this afternoon was the AMD 8.38.6 display driver. Introduced in this driver was official Red Hat Enterprise Linux 5 packaging scripts. Fixed in this driver was moving a video window between two monitors in a Big Desktop configuration no longer crashing the X.Org server and playing multiple videos when TexturedVideo is enabled no longer results in corruption.
It's a very sad release
