Low elevation airports black squares on tarmac SU5 v18.15

I have also been getting this checkerboarding on head turn in VR, noticeable mainly at airports and sometimes over the sea (picture in linked post)

Black checkerboard effect on ground when turning head quickly

Hi, One other issue I have since SU5 that I have not seen mentioned is terrain being rapidly drawn in against a black checkerboard when turning head quickly. It happens most commonly when my system is under heavy load at an airport, but weirdly ocean textures also seem very susceptible to it even when under low-medium load. Is this a bug or expected behaviour of the new SU5 culling which simply signals that I need to reduce my graphics settings (or slow down my head )? Thank y…
