           Summary: xv output slow and causes wmaker screen corruption
           Product: xorg
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: aeriksson at fastmail.fm
         QAContact: xorg-team at lists.x.org


Starting "mplayer -vo xv -hardframedrop anyfile.avi" cuases wmclock and
wmcpuload to show garbled icons.

Additonally, the video playback is unbearably slow, circa one frame every 5
seconds. Back when 2.6.29 was shipped (at which point I believe nouveau was
without ttm), xv playback was super smooth.
