Overlay mouse offset

Whenever I open the overlay while playinh, the mouse cursor is shown, but when i click, it's like it's about 50 pixels to the right and about 60 or 70 pixels down, making it really annoying to click anything on it. I think it's a scaling bug, because the closer the mouse is to the top-left corner of the screen, the less difference there is between the visible cursor and where it clicks.

Edit: I tested it while playing other games, and it only seems to happen when i'm playing Monster Hunter World.
