Well I’ve seen these green sun-shine-through clouds over grassland in in the Alps, Schwarzwald Germany, Madeira… Norway… there isn’t much agriculture or crop surveys there.
Real texture issues do exist in MSFS !! match errors !! but they are local (like Isle of Man) and I think technically speaking: it’s faulty sat image combinations, like mixed daylight conditions in the MIP-levels of the texture.
There have been complaints about a green hue overall, at some places. But the above image is no proof for a “texture bug”, unless you’d want them to rebuild part of their atmospheric lighting system. Which was quite an accomplishment, if you ask me…
