Graphic Bug: Seeing the rain through the world

Graphic Bug: Seeing the rain through the world

What I expected to happen was...:
While under trees or under the ground I should not see the rain falling from the sky through blocks.

What actually happened was...:
When I am looking up and moving my POV occasionally I can see the falling rain from quite far up through blocks, 

Steps to Reproduce:
1. When the weather is raining. Look up and look around.
2. Causing updates by mining blocks may help as I have found this to be unstable and difficult to recreate even in the same session of playing.
3. Pausing and changing windows may effect this as well.
