--- Comment #15 from Marek Olšák maraeo@gmail.com 2010-08-05 16:44:32 PDT --- I have tried everything in r300g. Flushing and invalidating all caches, flushing command stream after every draw operation and re-emitting all state, nothing helps.
Chris, considering what you say, I think this is a kernel issue, not an r300g issue.
