Switching between fullscreen and windowed using my windowmanager (hyprland) made the game freeze when in fullscreen and offset the curser when windowed. Now I start the game in windowed fullscreen and I just don't touch it again while playing.

The mouse input is very weird. Moving the mouse to the left pans the camera to the upper left. Moving the mouse to the right pans the camera to the lower right. Moving the mouse up and down does nothing. I've resorted to playing with controller, which works fine. Not sure if this is a linux issue, since I've read similar things in forums.
