The lakes are rendering through everything, specifically lakes the ocean doesn't do this.
Tried with and without shaders
turned off/increased overlap in BSL/distant horizons independently
maxed out render distance
Distant horizons RD 128-512
Quality low to extreme
Latest stable/nightly build
Deleted distant horizons folder and regenerated without shaders on/shader enabled
Tried all transparency options
Non colliding options
I have sodium, iris, immediatelyfast, Indium on 1.20.1
Didn't see people posting about this particular water issue but it's annoying going up a hill. Can even spot a 2nd layer of water floating over the lake from the ground if my render distance is low enough.
Turning off distant horizons removes the issue
