image of what you can see on screen

I get scrambled output on screen as soon as World of Warcraft (2.4.3) starts;
only the output is scrambled, it seems the card renders the image correctly in
X (a screen capture and a snapshot taken with a camera at thesame moment have
radically different appearance).

Other visible defects are already covered and worked around in other bug
reports, but this is actually a first.

Results are identical whether I use:
Catalyst 8.6 or 8.7
Wine 0.9.58, 1.0.0 or 1.1.2
d3d or opengl rendering

In the case of Catalyst 8.6, scrambling stays even after WoW and Wine stop; the
system will eventually crash. 8.7 actually recovers a little while after
application shutdown.

My system is Mandriva 2008.1 x86-64 Free, running on Athlon X2 with 2 Gb of DDR
RAM and a Sapphire RadeonHD 4850. Connection to screen is by DVI, I tried both
ports.

Could this actually be an Xorg bug? What can I do to test?
