We have seen much better behaviour in other desktop environments (e.g. Gnome 3 or KDE), where EVDI is given much more accurate information.
I have installed Gnome 3.20 on Ubuntu 16.04 and am happy to report that CPU usage has dropped dramatically (it was at around 180%). I shall report on stability once I've used it a bit more. Previously my external monitors would freeze regularly with killing the main displaylink process and unplugging the dock the only way to turn them back on.
