Subject: R300: output corruption with gl apps


Hi,

recently the output of any GL application (glxgears, googleearth,
nexuiz) is completely corrupted.

The whole window is flashing, with bars running up and down like on an
out-of-sync TV. The upper left quarter is filled with a green and blue
flashing square. The remaining parts of the window usually show the
background that was there before the window was opened.

Only the window is affected, the rest of the screen is ok. No error
outputs are found on stdout or in Xorg.log. My setup worked before, I
don't remember, which change introduced this error, though.

card: ATI FireGL Mobility T2 (M10) NT (AGP). 
kernel: 2.6.22.5
video-ati: 6.7.194
xorg-core: 1.4
mesa: 7.0.1

Is this some known bug?

Regards
A.
