I don't think it's the buffer problem (which, incidentally, should finally be fixable sensibly in libva2 soon), because that ended up manifesting as leaking memory.  It's also not a problem for Intel (I've already been running that for a long time to test).  Maybe some other sort of handle on the Mesa side?  I'll investigate further tomorrow.

Yep, checked with the updated Mesa postproc patches + libva2 fixes and it all looks good now.  (And colours are even correct, yay!  I still need to look into why the default comes out wrong with the postproc bits for that on Intel...)

Thanks,
