Default I'm also experiencing this issue

I'm also experiencing this issue on a Dell XPS 15 9560 laptop with a Dell D6000 dock. Laptop screen sitting to the left. 2 x HP L2445 monitors (1920 x 1200) middle and right.

When mouse cursor gets near right-hand-side of middle monitor or left-hand-side of right monitor it flickers and 'jumps' to the other monitor. Sometimes you can see it displayed on both monitors at the same time.

I just upgraded Ubuntu to 20.04 and so I had to update the DisplayLink driver to 5.3.1.34.

I also experienced this same problem with previous driver versions too. Displaylink driver version Release: 4.4 (17 Oct 2018) on Ubuntu 18.04 was the last driver version that didn't have this issue. And so it's been what I've been using since I got the laptop and dock. It was actually quite solid.

Something got broken after driver version 4.4 that causes this issue.

[ removed: I'm also getting sync drops with the newer driver too. Driver version 4.4 did not present any sync drops.]

added: I made a change and not getting the 'screen-drop-out' issues now. It seems like this thing was an old, old, old bug that still hasn't been remedied years later. Urgghhhh!!! Here are the notes I had in my old pulse audio /etc/default.pa file from years ago which I found and applied to my ubuntu 18.04->20.04 upgrade and seems to have fixed the intermittent screen-blank issue - so far, at least;

# GavinE - disabled because this was causing havoc with my D6000 dock! The audio would power off and shut screens of too!
# see https://github.com/displaylink-rpm/d...rpm#dell-d6000 and
# https://displaylink.org/forum/showth...5116#post85116 spcifically https://displaylink.org/forum/showpost.php?p=85116
#load-module module-suspend-on-idle

So just the ridiculous mouse cursor issue left to fix it seems.

I've included logs from the support tool.

@DisplayLink, is anyone investigating a fix for this issue?
[edit: hellloooo?? Is there anybody out there? ]
