           Summary: Textured video garbled until glxgears is started
           Product: xorg
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: mblaesing at gmx.de
         QAContact: xorg-team at lists.x.org


Hello,

when I start a textured video output, I get the output you can see in the
picture (in the left window the same video is playing via XV - which is not
shown of course) on the right. If I then start glxgears, the video is shown
semi correct. This means, that the video looks, as if every second or so
picture is shifted approx 1 pix to the right. So the video "wobbles" right and
left.

For the second part I'm not sure whether this is a second bug or the same
source, so for now I won't open another report.

This is the relevant part of the xorg.conf:

Section "Device"
        Identifier      "home"
        Driver          "radeon"
        Option          "GARTSize"              "128"
        Option          "AccelMethod"           "EXA"
        Option          "MigrationHeuristic"    "greedy" # Else XAA is much
faster!
        Option          "TVStandard"            "pal"
EndSection

and I define a Virtual Size of 1680x2100 (this is an radeon 9600, so I get dual
head with accelerated 3d on the whole desktop)

Thanks in advance

Matthias
