This bug isn't nouveau specific. It's either a bug in EXA or in pixman. I'm not
sure which, so I'll assign it to EXA for now :p

The corruption also appears when using EXA "greedy" with Gnome Nautilus. Any
redraws for background damage after moving or closing a window, the damage is
always drawn using top left (0,0) of the background. Switching to EXA "always"
fixes problem.

This is on a R200 running xorg-server 1.4 release and xf86-video-ati current
GIT so definitely not a Nouveau issue. Note bug still assigned to Nouveau
Project project though.

The fallback case in exaFillRegionSolid needs to be fixed to use something else
than fbFillRegionTiled, so the GC is taken into account properly. Any takers?

Probable fix, against server-1.4-branch

Does this patch fix it?

I tested the master branch by adding
  pPatOrg->x != 0 || pPatOrg->y != 0
to the condition which fixes the issues for me.

Fixed on the master and no-pci-rework branches. Leaving this open though and
making it a blocker for 1.4.1 so it'll hopefully end up there.

Debian xorg-server (2:1.4-3) works fine. It got the fix :
  * Add 08_exa_fix_exaFillRegionTiled_fallback.diff by Michel Dänzer to punt
    on fallback case not handled correctly in exaFillRegionTiled (backported
    from master's c7d6d1f5); closes: #444203.
