Summary: "tile offscreen pixmaps" causing graphics corruption on
NV50?
Product: xorg
Version: unspecified
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Driver/nouveau

Hi,
(Shamelessly Cc'ing Ben Skeggs as he authored the offending commits)
Am seeing some graphics corruption on nouveau with my 8600 GT consisting of odd
black or white speckles on some widgets.
It's especially noticable on the folder list of the Claws Mail mail client, but
also appears as white horizontal lines in a gnome-terminal window after some
time. Please ask if a photo would be useful.
I've bisected it as follows:
* Working version:
- drm
401f77a2ef1d55feaccc13cdae1e5379f4cfec7e
i915: official name for GM45 chipset

- nouveau

exa: pass window coords to m2mf-based UTS/DFS

* Broken version:
- drm
c7ed2c67916ee8058301c53b9d4690d81728fb95
nouveau: interface changes for nv5x 3d

nv50: tile offscreen pixmaps

I don't know whether it is nouveau or drm commit that is causing the issue -
the "bad" nouveau commit requires a newer drm than its working neighbour (bumps
NOUVEAU_DRM_HEADER_PATCHLEVEL). I would guess it was the "tile offscreen
pixmaps" commit though.
Am running Linux 2.6.25/2.6.26 on x86_64.
Regards,
