To be honest the greatest problem is Beach biomes which have an unnecessary amount of Fog. The expected behaviour would be a neutral amount like Plains.
Yes, i noticed the water not as blue. Wondered if the sky wasnt being reflected, and saw that everything but the sky was reflected. Would it be better to change the title to “water surface not reflecting sky?”
Every instance of this bug I've seen has been on Playstation 5. On other platforms the water looks normal sometimes, including Playstation5_emu (At least from personal experience seeing footage on 1.21.90.26 Preview)
