The ID I see in the logs is "ATI Technologies Inc 760G [Radeon
3000]", FWIW. The "780" bit looks to be an audio controller
personality on the same silicon.
Maybe the hardware is just a hair removed from working to spec?

They revealed themselves as a problem with the out-of-the-box
xscsreensaver setup. They will also cause issues run with -root
without any xscreensaver in the picture. The root window they're
drawing into in each case is 1920x1080. No compositing window
Thanks for looking at this!
