One interesting thing that I saw, in Garadar. I was standing on the hill near the flight master, and close to one of the downward paths, right up against the short wooden "pillar" topped with a brazier. The pillar and brazier were repeated just beyond the "real" one. The lake was beyond that, so I'm pretty sure it was related to the "water" problem (and it did go away when I switched that setting to "low").
