Weird black splotch near water

I started noticing this bug after the new update with the vibrant visuals. I tried to turn it all off, didn't work, turn it all up to the highest setting, didn't work. Loaded up all my worlds and it's effecting all of them, past and new. I made a brand new world to test it and boom, black splotch taking up most of my screen if I'm ever near water. I think it's the water, usually if it's flowing but it's happened on non flowing water. It happens even if you're a decent few chunks away, maybe it's because it's in render distance? It's weird and I'm terrible at explaining things so I got videos and a picture
