Blocks behind Barriers don't render

While building a map, I have noticed that sometimes blocks do not render while viewing through barriers. Although I do not know how to recreate this, I can tell you that my barrier walls are 4 - 5 layers thick. I'm also on a superflat world. I attached a few pictures of this bug below.

I am surprised that nobody else reported this, so I must be missing a post. Please tell me if this is a duplicate because I can't find another report matching what I see.
