Description andreas.schmeja 2024-07-03 20:25:37 UTC 
SUMMARY
When moving the mouse between displays sometimes a copy of the cursor gets left behind on the previous display
The copy disappears after a while 
This does not happen when a window is touching the edge, but only directly on the desktop

This is only a visual effect and the mouse remains usable
The effect does not appear on screen recordings
I am using a Lenovo USB Dock to connect to the monitors


STEPS TO REPRODUCE
1. Use a laptop with two monitors connected through a DisplayLink USB-Dock
2. Move mouse between two screens


OBSERVED RESULT
A copy of the cursor remains on the previous screen


EXPECTED RESULT
The cursor passes to the other screen without leaving a copy behind
