Mouse movement duplicated on second monitor

[github-k8n]

With my current settings (see below) it seems that sometimes my mouse movement on the right monitor (Linux, Output A) is duplicated on the left one (Windows, 2 monitors, one builtin and one connected, the connected monitor is exactly the same as the one from the Linux system. Only mouse movement is duplicated not any clicks or keyboard entries. I can fix it by moving the mouse all way to the left (over the connected monitor of the Windows system and on to the builtin monitor) and then back again to the Linux system then everything is ok again for a while. I have a suspicion that it could be related to either the Cursor park position or the Screensaver mode.
