EDIT: It might not actually be when generally looking at water. I'll need to test more.
Playing on MC 1.19.2 with Fabric+Iris.
Minor but noticeable and annoying frame drop when water is on screen, using Vibrant shaders medium 1.50.
The same issue does not occur when using Vibrant shaders medium 1.40.
No idea which settings could change this or if it's a bug. My reflections settings are the same between both versions so I'm not sure.
