While using 3 displays on a Windows 10 laptop, I noticed a problem wherein the cursor would get stuck on the edge of a screen at the border between that screen and another.
(You'll have to forgive me; I'm having trouble capturing a screenshot that includes my cursor :-/ )
I traced this back to a gap between the displays in the Display settings.
Removing this gap removes the issue with the cursor getting hung or stuck between screens.
This is completely reproducible on my system.
