Mouse cursor appears on the borders of my screen

Hi!

I’m working in Unreal Engine 4.27 on a game that is nearing the finish line but I have to face a recurrent problem I don’t know how to solve.

The mouse cursor is showing up when my mouse reaches the borders of my screen (this happens in full screen mode)

You can see it quite often on the top and left of the screen as I’m moving my mouse onto its edges.

I can guarantee that there’s no Show Mouse Cursor set to True on the Player Controller.

And I also tried setting my “Set Input Mode” nodes as such:

Without any success. The bug keeps appearing. :frowning:
