Stephan Fabel:
1) Could you please attach a screenshot or screencast of the flickering via
https://help.ubuntu.com/community/Screencast ?
2) Could you please cross post this issue upstream to DisplayLink Support
following their guide at
http://support.displaylink.com/knowledgebase/articles/757047-how-can-i-report-ubuntu-issues-to-displaylink
? While it may end up being root caused to a Ubuntu issue, more eyes on the
problem wouldn't hurt here.

Title:
[Dell XPS 13 9360] Mouse cursor flickers with one external monitor
connected via HDMI+Wavlink WL-UG39DK1V
Status in xorg package in Ubuntu:
Incomplete
Bug description:
When I connect my laptop to my DisplayLink based device with USB
(Wavlink universal USB 3.0 docking station
https://www.wavlink.com/en/product/150 WL-UG39DK1V), and connect the
Wavlink to my AOC E2775SJ Monitor via HDMI, the mouse icon flickers.
Only if the mouse is on the laptop monitor, it can vanish for several
minutes, but remains active.
Animations/overlays or typing inside a Chrome window causes the mouse
pointer to flicker more often. If there is no interaction or
animation, the mouse pointer remains static and drawn.
Monitor 1: 1920 x 1080 - Laptop's Native Monitor
Monitor 2: 1920 x 1080 - DisplayLink (USB) connected AOC E2775SJ Monitor
This issue doesn't happen if I don't connect my laptop to an external
monitor via the Wavlink device.
This issue is reproducible with DisplayLink driver 1.4, and 1.3.54.
This issue is reproducible with Ubuntu 16.04, 17.04, and 17.10 x64.
