https://bugs.freedesktop.org/show_bug.cgi?id=40739

           Summary: Weird pixels on Nouveau chip Nva3 Nvidia Quadro FX
                    1800M
           Product: xorg
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: gorilla.maguila at gmail.com
         QAContact: xorg-team at lists.x.org


When using nouevau driver you can see weird pixels and extrange colour
transitions on screen (See image attachment).

I have taken some pictures with my mobile, because If I would enclose a
screenshot under nouveau you wouldn't appreciate these visuals effects.

It's not happening when using the blob.

I'm using mesa 7.11 under kernel 3.0.4 in archlinux x64, I think its been
happening every time I have used nouveau driver, If I am not mistaken since
kernel 2.6.35.

I don't see weird pixels, but I do see the colour transitions, i.e. that
dithering seems to be disabled - http://nouveau.freedesktop.org/wiki/Dithering
