Yes, I'm sure, I did another test to check, nothing gets added to my dmesg even
after it shows up.

Can you try some other resolution than 1680x1040 and see if it has issue too.
Specially something like 640x480

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.
