My laptop's touchpad is emitting joystick events

Using my touchpad seems to act as if it's a joystick - If I touch the edges it acts like I've pulled the joystick to the far edge of its movement, etc. sort of like how a steam controller's touchpads work when emulating a joystick. However, it also just acts like regular mouse input so it's only noticeable in games that detect joypad input.

This happens regardless of Steam being activated. I have used DS4 controllers on my laptop before but this happens regardless of them being connected.

Manjaro and GNOME btw. Happens on x11 and Wayland.

Any ideas?
