           Summary: [KMS] Xvideo window not refreshed on s-video port
           Product: xorg
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: bjaglin at free.fr
         QAContact: xorg-team at lists.x.org

When using VLC on the s-video port set up in dual head, with KMS enabled, the
video is not updated. The same config works fine with UMS. Disabling XV_VSYNC
has no effect. No error message when the video freezes.

I am running a rv250, git latest libdrm/mesa/ddx, 2.6.32 + drm-radeon-testing.
Compiz is disabled.

01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV250 [Mobility
FireGL 9000] (rev 02)

I have found two workarounds so far:
- use mirror mode
- move the window so that it is just a few pixels away from the left border
(LVDS side), or even more so that part of the window is on the LVDS screen.
