In the Vibrant Visuals experiment, small waterfalls contain a visual error where it looks like the game tries to create underwater fog around outside the water despite you not being in the water? It’s super weird, I’m not exactly sure what’s going on, but hopefully the video attachment does a better job at showing what I mean.
Steps to reproduce the issue:
Find a one block waterfall naturally or you could probably reproduce it by creating it yourself. If you want to find the same one as me, the seed Is 6463538860296125400 and the coordinates are -176, 73, -735.
The visual bug SHOULD occur.
Expected result:
The water should look and behave as normal.
Actual result:
The water is visually bugged out.
