Fix glitching mouse pointer in Ubuntu/Arch/Debian
I've tried the DisplayLink driver using the recommended os (Ubuntu 16.04). After connecting a secondary display (1080p) using USB-C, I had a trail of blinking mouse pointers following the real one and all the animations started glitching.
When moving the mouse over any Window except the Desktop, there would be a glitching square (about double the edge length of the mouse pointer sprite) containing the desktop background around the mouse pointer.
I've also tried Arch Linux (using the AUR package) and Debian 9 (Using the Ubuntu package) and they show the exact same behavior.
On the three operating systems, I've tried Kernel versions 4.19 and 4.20, both having the same issues.
I have a Thinkpad P1 with a Xeon E-2176M CPU (Intel UHD Graphics P630) and a Nvidia Quatro P2000 Mobile (GP107GLM). I suspect this to be an error related to the hardware I'm using; partially because I tried different operating systems and different kernel versions.

I have the same issue in Linux Mint.
