Duplicate status does not seem to be relevant, both because the issues described are different (flickering vs. completely black screen) and because the other bug is not marked as "Won't-fix" because it was reported on Artful.

I can confirm I have some form of this problem on an LTS release (16.04.5), computer is desktop and I only have the single monitor (Dell P2415, connected with high speed HDMI cable). Flickering happens intermittently (seems to happen more when I hover on icons in the launcher).
