7.7.1 doesn't even build against xorg-server 1.19, let alone run with
it. So I suspect downgrading the driver to 7.7.1 also downgraded
xorg-server to 1.18.4.

Your problem is probably the same as https://bugs.debian.org/846779 , a
xorg-server regression.

That probably avoids the problem because DRI3 is enabled by default now.
