It seems to look quite ok (I'm not able to get a pic with xmag). Introducing some delays fixes most (except the same 5, plus sometimes a 6th) errors (down from 2900 or so). I think it's a problem with texture caches or something, since always the same texture offset is used but the texture changes (weren't there still errors with radeon and xorg 2d render which might be related ? Maybe not though.). In any case, if always submitting the tex state atom (thus not using the R200_DB_STATE which will notice that nothing has changed), all errors disappear, even without delays. Hmm... Maybe writing one of these regs (txoffset?) triggers a tex cache flush or something.
