--- Comment #15 from mirh mirh@protonmail.ch --- AMD itself recommends avoiding the binary driver, if you haven't specific professional necessities.
Said this, AFAIK buffers were quite reworked in 2.1-2.3 by Henri (including some "stalling avoidance"). c1032e977bb9f850e3aea28dd79e3d7c2244cd6c instead may possibly explain some mesa-nvidia difference.
So my educate guess would be this got fixed. Otherwise anyway, for any issue still left with buffers, I always tend to point my finger towards bug 44315 and wine-pba.
