I get screen corruption and general problems as well.
Tried both free and proprietary drivers, 12.04.2 and 13.04.

The nasty workaround for me is to connect an external HDMI monitor, which helps /fix/ the problem.
When Ubuntu tries to clone the laptop screen, this ends up fixing the screen corruption, when using the fglrx driver (For both the HDMI display and the laptop screen). I can then disconnet the HDMI display and the laptop screen continues to work well.
When I use the radeon (free) driver, the HDMI display works find, however the laptop screen shows artifacts (either 'split' screen or flickering).

Since both the free and proprietary drivers exhibit similar behaviour, it does look like a common kernel issue.
Will try newer kernels.
