--- Comment #14 from Ilia Mirkin <imirkin-FrUbXkNCsVf2fBVCVOL8/A@public.gmane.org> ---
I believe the issue is mostly resolved by:

https://patchwork.freedesktop.org/patch/270609/

There's a lingering issue, which I don't think was truly being hit, but fixed
by:

https://patchwork.freedesktop.org/patch/270610/

Of course when I went to test these patches with xonotic, I was immediately
confronted by the fact that we don't handle 3d transfers (which ~never used to
happen before, but some recent improvements have made it a thing that happens a
lot more often). I quickly hacked around that with the below patch, but that's
obviously not generally acceptable.

FWIW xonotic looks terrible on the nv34 -- all the colors are messed up, and
maybe some of the geometry too. But it's the same with 18.3.
