Heh don't ask me, ask any of the people that actually have a clue like Maarten
or others on IRC :)

Did you link this corruption with nouveau_exa_download_from_screen or
nouveau_exa_upload_to_screen that you mentioned several times ? The fallback to
memcpy-based transfer there ?

You could enable NOUVEAU_FALLBACK in nouveau_local.h , and then add a few
ErrorF or NOUVEAU_ERR in strategic places to see if you can link the
corruptions with some code path.
But I don't know if that's a good idea and approach to the problem.
