Indeed, the resolution is the problem,
running any application in my system resolution (1680x1050) breaks rendering, something like 640x480 has no problems. It also corrupts things like glxgears while I resize them (from any resolution).
What I mean is, glxgears gets corrupted if I resize its window while it is running, it displays corrupted blocks
I am also seeing this resize corruption on HD4890 (native res = 1920x1080).
Some demos seem to start corrupted - gearbox starts with band at top.
Projtex - less reliable, may need other demos run first, but may start totally corrupted then correct when a key is pressed.
