The specular reflections of water are visible on top of all blocks, player hand, player model in 3rd person, etc.

Using Distant Horizons, possible reason for error.

GPU: Nvidia RTX 3060 (mobile)
OS: Windows 11
MC Version: 1.20.1
Shader Loader: Oculus
Shader Version: Bliss Shader Main (In development version)

Some other mods in use: tetra, create, quark, biomes o' plenty.

Turning off "World > Water Settings > Specular Reflections for Water" is the only fix I have found.

Reset settings and issue was fixed.

commenting because i know what it was; you turned overdraw prevention off. that's why it did that.
