           Summary: Radeon timing bug (tearing)
           Product: xorg
           Version: 6.8.1
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: Driver/Radeon
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: drzeus-bugzilla at drzeus.cx


FC3 with Xorg 6.8.1. Radeon 9700.

This problem has plagued me for as long as I've been running Linux with this
graphics card. (XFree 4.3.0, xorg 6.7.0 and xorg 6.8.1).

Whenever there is a lot of display activity I get junk all over the screen. This
seems to be related to how the hardware is handled since I cannot do a screen
shot of the effect. Basically it smears out random stuff from the screen over
random portions. The "randomness" in this changes constantly so it appears more
or less like static over the screen.

Scrolling or dragging large windows will cause this effect.
Video will cause this effect to the extreme. The smaller I make the video window
the more of this effect shows up. Above a certain size the effect stops. The
higher resolution of the movie, the more problems (and larger threshold size).
