Mouse slowness when certain app is active

[derchrisuk]

Hey folks,

I'm trying to figure out a weird issue I have on a MacOS 11.6.1 client.
Server is Windows 10.
Mouse is running smoothly when switching to the MacOS desktop.
Only when a certain application, in this case Webex, is running the mouse is stuttering.
When I switch to a desktop with another app, like a Web-browser or something else all is fine.
But one I switch to the desktop running Webex the mouse is not running smooth anymore an is jumping every few pixels.
Trying to figure out ways to troubleshoot this.
It seems this has been introduced since I updated to 11.6.1, coming from 10.15.
So this could also be a bug with the latest 11.6.1 MacOS.
Any help much appreciated.
