I recently upgraded the Displaylink drivers from 1.1.62 to 1.2.65.
Since the update I experience glitches. I attached a screenshot to outline the problem. I simple moved the browser window around.

My current setup:
Ubuntu 16.04 with XFCE as desktop environment.
Intel Corporation HD Graphics 520
Linux 4.4.0-45-generic x86_64
ThinkPad USB 3.0 Pro Dock
X.Org X Server 1.18.4
I'm willing to debug/assist with the developers to resolve this issue.
Update:
---------
I reenabled the compositor under 'Window Manager Tweaks' => Compositor. See this video
