To try to confirm this, I just downgraded to X server 1.15 and the
problem has indeed gone away.
However, doing so also required I downgrade xf86-video-intel from
2.99.914 to 2.99.910, so the INtel driver could also be the source of
the problem. Michael, are you seeing this on a system with an Intel GPU?
