When banner placed on another banner with a snow layer under you can see through the world.

For what ever reason when you place a banner on a banner with a snow layer infront of the initial banner you can see straight through the world. I was trying out some banner for my minecraft single player survival world when I accidentally placed a banner on to another banner with a snow layer in front and it showed straight through the world. I was able to replicate this again, so I tried logging out and back in. It was then still occuring when the action was played. Although it only lasts a few seconds, I thought to report it here just in case.
