           Summary: Graphic Corruption on HD 4570
           Product: xorg
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: who-ah at hotmail.com

When using the latest "radeon" from the repo or the git version on Archlinux
x86_64 with ATI Mobility Radeon HD 4570 graphical corruption appears as soon as
the driver is loaded with KMS enabled, covering up the whole screen -
diagonally moving colorful stripes. They don't appear when software capturing
the screen, so I took a photo: http://img849.imageshack.us/i/s8300438.jpg/ .The
same happens with the latest Ubuntu 11.04 Live CD.

One more person with the same card is reporting the problem,
https://bbs.archlinux.org/viewtopic.php?id=115932 ,who also made a video:
http://www.youtube.com/watch?v=s0-kYZSHRG8 . He reports it to be caused by
overheating, but I don't think so, because the stripes intensity is random on
every boot and sometimes the screen is clear (something like 1 out of 10 boot
ups). I don't have overheating issues myself.

The graphics performance is overall great, in spite of the artifacts.
