It looks like the same problem as bug 104668 and bug 104777. 4195eed961ccfe404ae81b9112189fc93a254ded fixes the problem.
Well, this is kind of expected, because the current git master does not have that bug.
However, the real bug I am reporting here is that the above fix is not ported to the Mesa3D-18.0 branch.
You definitely do not want to make a release containing that bug.
