I'm running Suse 9.1 (with all the latest updates from Suse)
XFree86 version 4.3.99
on Intel P4 with Radeon 9800 Pro 128 MB
ATI Driver 3.14.1

When there is a window with black background (or black desktop)
I get a lot of thin Technicolor lines that are going from left to right
and appearing at different Y position on the screen.

Any idea how to fix this?

If anyone has the same setup and does not have this problem could you please
send me your XF86Config file.

Thanks.

Obelix
