           Summary: Display corruption on 7600GO
           Product: xorg
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
        ReportedBy: chalserogers-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org
         QAContact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org


With current git as of 2007/07/19, nouveau suffers from quite a lot of
graphical corruption, which gets cleared up with a redraw (moving a window
over, for exampl.).  Screenshots, dmesg & xorg log attached.

Interestingly, some of the graphical corruption contained part of a screen
image from a previous boot (the screenshot was taken after a warm-boot).  Maybe
some of the framebuffer is getting memory copied from incorrect places?

Adding Option "MigrationHerustic" "Greedy" to the Device section in xorg.conf
very nearly eliminates the corruption.  The desktop window still starts up with
a corrupted lower half, but I can't see any application corruption anymore.

I still see this, although to a lesser extent, with Iceweasel particularly and
current GIT (2007-07-23) and MigrationHerustic "always".

ahuillet's branch displays no application corruption, but still gives a
corrupted desktop.

It seems this has been fixed somewhere along the line.

I'm now using Xserver 1.4, and current nouveau, and this problem is gone.
