Camera getting stuck at the horizon

[johnniehard]

I'm having some trouble with the camera getting 'stuck' at the horizon. I can turn left/right just fine, but while looking up/down the camera stays stuck at the horizon until I move the mouse a lot in one direction (10+ cm). Then it suddenly gets unstuck until I move to the horizon, where it will snap into place again.

This is my setup:

I've added this project via the Godot Asset Library from within the editor, set up a scene where I added an instance of the controller and a simple floor the player can stand on.

I'll happily provide more information if necessary/helpful.
