Textures disappearing in 3rd person, when camera is above a block

Background info:

After swimming around a bit in third person, a visual bug happened when my camera went over a block to the side of the player. Later, I found out this occurred out of water too (see screenshots).

 

Expected:

For the game to render the sides of blocks as usual. 

 

Actual result:

The sides of blocks disappeared, as well as causing some underwater visual glitches.

 

How to reproduce:

1. Go into third person.
2. Move around to a location where the camera can be placed above a block which is above and to the side of the player (see screenshots).
3. Observe...

Extra notes:

Screenshots show normal, the visual water incident and the side of blocks incident.

Device is a Oneplus 3t.
