Unloaded chunk has floating water

Chunks load very slowly and in big chunks (of chunks).

If you go into the unloaded chiúnks you will find wierd spots of water floating.

This also happens when you go into the world and the chunks are loading. It loads very slowly but the strange water is not visible. You can hear it, though.
