Hmm, something is even more broken.
I can't even open a session now under Ubuntu 16.04.
Now using older Ubuntu release that uses nouveau driver 1:1.0.11-1ubuntu2.
We'll see if bug happens again: [Some glyphs drawn consistently wrong, bug comes and go](https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1547077)
