Original GitHub issue: https://github.com/debauchee/barrier/issues/524

Operating Systems

Server: Ubuntu 19.10 eoan
Client: macOS 10.15.2 Catalina

Barrier Version

Server is 2.3.2 from the jonathanf PPA
Client is 2.3.2

Steps to reproduce bug

Fairly often (several times per hour it seems) the mouse pointer on the macOS client will "go crazy" when trying to move it, as if macOS and Barrier and both trying to reposition it. The mouse pointer hops around and is jittery. Sometimes clicking on the touchpad on the MacBook fixes it.

I have no idea how to reproduce this at present.

Other info

It seems like the problem started to occur under macOS 10.15.2, maybe also under 10.15.1
Had the problem with server 2.3.1 too.

Same here... using Mac 10.15.2 when I move the cursor off-screen to next device I can still see it moving up and down on my mac screen while moving on my windows laptop.

Using Mac Mini late 2014? and Window laptop

It does still happen very occasionally, but a lot less frequently.
Previously it was several times a day, now it seems like it's once a week
or so.

I confirm it is still a problem on a client computer. There appear to be 2 cursors jittery splitting and uniting. Sometimes, the cursor disappears and appears back on the server.

[2021-03-15T23:41:40] DEBUG: hiding cursor
connected to server

I initially suspected LAN problem (an ethernet and wifi adapter either a client or server connected into 1 LAN at the same time), but I can confirm this is not the case now.

<!-- gh-comment-id:799794656 --> @AlbertBaubleDeem commented on GitHub (Mar 15, 2021): I confirm it is still a problem on a client computer. There appear to be 2 cursors jittery splitting and uniting. Sometimes, the cursor disappears and appears back on the server.
