Mouse drift down with gamepad

Hi!
I’m trying to make menu navigation with keyboard/mouse and gamepad. For gamepad navigation I use get/set mouse position (see the image below). The problem is that, for any reason, when I’m using gamepad and the cursor is at lower half screen starts drifting down. I checked the clamp value and it’s 0.0. Any idea?

Go there with the gamepad and start drifting. Disconnect the game pad - if it’s not drifting anymore, you may have a worn-out drifting gamepad. Test it with another one to make sure.

Before throwing it away, you could play with deadzones.
