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.

It is likely a circular buffer somewhere in the stack of display code for redrawing elements behind the mouse cursor that is failing to stop where it should.

I have found that adjusting the mouse speed (Settings->Devices->Mouse & Touchpad->Mouse Speed) changes the degree of irritation from the defect. I find the least irritation from having it set to the highest (fastest) setting. That's partly because I have a TrackPoint for a mouse. When the setting is towards the middle, you can end up with a big ugly trail of mouse pointers.
20191223 - i'm getting this after updating from Cinnamon-Tina to Cinnamon-Tricia... however i note below in the comments that 19.2 has also had its issues but i havent noticed them - the driver i'm using is 5.2.14 tried an older one but that wouldnt work (5.1 and 4.4)

Seeing the same issue with Ubuntu 18.04.2 and 18.04.3 running gnome-session and kernel 4.15.0-54, but I am not seeing this issue with gnome-session-flashback.
Edit: I do not see this issue at all with initial/first release of Ubuntu, 18.04.0.
I have the same issue in Linux Mint 19.2.
