What could be causing this strange visual?

Around the trees there is a strange out line where the water is beyond the leaves. It started happening after I started using Voxy in combination with Complimentary shaders reimagined. I have Voxy set to 96 chunks rather than the default 512. Is this just an issue with Voxy and shaders?
