Yeah I'm very much aware of the issue, there's probably some gaps in our
understanding of how the tiled surface stuff works on nv5x chips.
However, the commit also allowed me to implement Xv and XRENDER
acceleration (the 3D engine *must* use tiled surfaces, it'll refuse
anything else), and the corruption is minor in most cases - so I decided
people could live with it for now.
I will note that I use the driver myself, on my main desktop machine -
so I eat my own dog food :)
We'll figure it out eventually, but as we have no nice docs like the
radeon guys it could take time.
Cheers,
Ben.

Alas, this doesn't seem fixed for me; I'm still consistently seeing minor
speckles on some widgets.
Ben, was you recent change to nouveau_xv.c intended to close this? If so, I'm
fairly sure this issue is different from any xv corruption.
Regards,

No, the Xv commit was unrelated. Did you, by any chance, see if you were still
effected by this bug with the patches listed at
http://nouveau.freedesktop.org/wiki/NV50Support?
An alternative to trying those patches is to use the "ng" branches of drm git,
and xf86-video-nouveau git and see if the corruption appears there also.
However, this isn't an option you'll want to currently use on a day-to-day
basis, it's very buggy still.
With either option you shouldn't see any rendering issues (though fwiw, I don't
see any without them), if you still do, there's something else going on with
you card that we'll need to track down.

Unfortunately, I didn't get around to looking at those patches. However,
sometime over the last few months it cleared itself up. You can probably go
ahead and close this bug now. Thanks again.
