I have a mouse cursor movement issue with the Multiplicity KVM. There is weird discontinuity on the screen.  It feels like some issue caused by screen scaling. There is a point where the cursor jumps back to the edge of the screen and there's constant linear offset with the cursor after that point. At the top left corner of the screen the offset is close to zero.

The HW configuration is quite difficult to explain, but basically I have two computers here and they are connected using KVM. There's one laptop that is using dual-screen layout and one desktop with single screen layout. I have one larger display which is shared between the Laptop and desktop, but usually only Desktop is used as a input source. In laptop the main integrated display is 4k, but currently. I'm using it in Full HD (1080) resolution.

Here's a video of the problem https://youtu.be/Gx99gKVfEVw
