3D Radeon RV370 (X550) garbled

[Brian Chadwick]

Hi,

F11 Beta

Desktop effects shows a garbled screen.

Using plain old metacity, starting glxgears gives a garbled window, 
although the terminal from which glxgears is started shows frame counts. 
(approx 1900fps)

changed accelmethod to EXA or XAA makes no difference.

Hardware is x86-64, Radeon X550 (RV370).

Xorg.Log.0 shows no errors.

glxinfo indicates R300 DRI rasterisation.

any clues?
