• Details:
  

The ocean surface can get a sort of flickering green screen-door effect when viewed at higher altitudes, but an exception to this can be seen at the "Forest Haven" island where, on approach, this effect can get much more aggressive (encroaches on the area around the island at times) and can even be seen while actually on the island. I don't have a comparison shot for this (the family Wii U is put away somewhere) but this green screen-door effect is definitely not native behavior.

Does this also happen with all graphic packs turned off?

[ThisNekoGuy]

I'll check that when I have a moment; I'm kind of physically blocked off from doing that in-game at the moment

[ThisNekoGuy]

It seems to specifically be the "Contrasty" graphic pack that's causing it, for some reason; and depending on the preset selected, the screen-door effect is a different color
For example, the "colorful" preset causes these light green ones and the "high contrasty" preset causes dark green screen-door effects
