Description Matthias Bläsing 2008-04-10 12:20:43 UTC
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

what version of the driver are you using?  Also please attach your xorg log and config.

I have a Debian SID System, run with mesa head, the drm from kernel 2.6.24.4 and the xorg driver from git (current master).

Can you try again with my latest commits to ati git?

Jay! I openend the same setup as in the picture and got a nice looking video in both windows without any more glxgears starting or so. The video does not wobble! So I would say the bug is fixed!

Thank you!
