I was going to my base and part of the entry is a tunnel filled with water. When I jumped into the water I could only see white, but when I went out of the water, everything was normal.

When I go into water, everything turns white and I can't see anything except mobs. It really makes it hard to navigate through water. When I'm looking at the water though, everything looks normal. It happens in my other worlds too. It doesn't happen that often, but it's annoying when it does.
