Have you checked your graphics settings make sure it’s set to full screen at your native resolution?
Have you tested your twist rudder sensitivity? Sometimes we don’t realise that when we move the joystick to bank the aircraft, our hands slightly twist the joystick to one side without realising and this slight movement moves the rudder. I set my twist rudder sensitivity to be -75% on both sides, and deadzone of 15%.
Not sure about the landing guides, I never use them since they’re a distraction.
