https://bugs.freedesktop.org/show_bug.cgi?id=37681

           Summary: Tearing with composite extension
           Product: xorg
           Version: 7.6
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: dack at ereomega.net
         QAContact: xorg-team at lists.x.org


See Ubuntu bug report for more details:
https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/600178

There is extremely bad tearing with both nouveau and nvidia proprietary driver.
 Tearing is present even without using a compositing window manager.  The only
way I've been able to stop the tearing is to do something like:

Section "Extensions"
 Option "Composite" "Disable"
EndSection

I'm not sure which component is at fault (XGL, composite, nouveau?).

I have tested both nvidia driver and nouveau under unity, classic, and classic
(no effects).  Changing driver makes no difference.  Single or dual display
makes no difference.

I just tried the Fedora 15 LiveCD, which also exhibits tearing.  With the 2
most popular Desktop distributions exhibiting such a major video issue, I would
think this would be getting more attention.

Same here on LG S900-U laptop, Nvidia 8600M GT, Kubuntu 12.04, both with
nouveau and Nvidia drivers. I hope it gets fixed. it is painful to look at.

Actually it's even worse on my end. Tearing does not go away on
nouveau's
drivers no matter what I do. Even with compositing completely disabled, opengl
video output still tears. The best I can do is enable opengl compositing with
compton or something similiar and enable sync to Vblank, but there's still
tearing at the top of any fullscreen video even with opengl video output.
I'm
on Arch with a Nvidia GTX 650. The tearing issue does not happen in the
proprietary drivers either. I hope this issue gets more attention as the
proprietary drivers have some other problems of their own for me.

Seems like tearing gone with Full Repaints VSync mode in KWin.
