Not meaning to come across as confronting, but we've answered this question quite a few times. It's an 11.3 issue. New shaders, and we've told everyone that if they choose to run it in 11.3, to do so at their own risk, as we don't support any X Plane beta's. We do know about it, but toto isn't going to do anything about it until 11.3 is out of beta, as things could change, or Laminar could even fix it on their end.
