Not sure, if that belongs here, but in the Florida Keys the shallow water detail is atrocious:
It’s just OK around the Fort at the end, anything else is a blurry mess from VFR height.
Edit:
It’s not only the Florida Keys but parts of the Carabean and most of the pacific archipelagios, except for bespocke ones like Bora Bora. Also visible in SU5.1 so not really a regression.
made a general bug report
