You can't use the trackpad to move the camera while the character is moving

When a character is moving (no matter which direction it is walking, gliding, sneaking, sprinting, or flying), you can only use the mouse to move the view, not the trackpad (even if the mouse is unplugged), but you can use the trackpad to move the camera when the character is stationary.
