Public bug reported:
It seems to be duplicate of both :
https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1641467
and

A - flickering in first display.
The zone starts just below the top panel and its height is about 1/7 of the
screen.
Flickering starts immediately entering the zone, even half of the pointer may
be flickering.
To the centre of the zone, flickering is more prevalent, up to completely
disappearing.
The flickering has a periodic pattern, which seems to be affected by the
windows displaying in the second (external) monitor !!
B - external monitor.
Some applications show really slow there. Worse case is HipChat (Atlassian chat
program), which shows fine as long as even a tiny fraction exists on the
primary display.
At the moment the whole window passes to the secondary, then even the scroll
bar has a delay of a second a move.
To check, I have played with the ~/.config/monitors.xml without success.
It seems that each configuration is saved there, even duplicates, after adding
the same external monitor and re-configuring it (absolute duplicate in
monitors.xml)
C. Side-effects and related phenomena.
Some times the "Screen display" control freaks, when enabling the external
monitor. It may freeze or insist to put them in mirroring. Most of the times it
just forgets a setup (although in monitors.xml) after adding a different
external monitor.
For each workspace, there is a different background, done with Unit5y Tweak
Tool.
All updates have been done, without effect.
