Public bug reported:
When using external monitors through DisplayLink, the mouse pointer
flickers, and a static box of display lingers around the pointer whilst
scrolling.
I am using Ubuntu 16.04 LTS on a Dell Inspiron 7566 with an NVIDIA
GeForce GTX 960 GPU. I have tried both the Nouveau driver and NVIDIA
drivers (390 and 384), and have the DsiplayLink 4.2 driver installed.
