Downgrading cairo from 1.12.2 to 1.10.2 (thanks to chithead pointing
https://bugs.gentoo.org/show_bug.cgi?id=409593) removed the artifacts.

Apparently this is still a nouveau issue though.

Re-used the latest cairo and attempted to use a workaround suggested in
https://bugs.freedesktop.org/show_bug.cgi?id=47266#c37 :

[  6206.704] (WW) NOUVEAU(0): Option "EXAPixmaps" is not used

But the glitches still appear.

The issue in bug 54883 has been fixed by updating xf86-video-nouveau to 1.0.3

Can you give it a go ?
