This bug is about beds!

There is a bug about the beds. And it really gets on my nerve. At one point, when you look at something with the bed's corner on the screen it shows that it disappears. And then on the bottom right corner, if you jump on that particular spot, it's not bouncy like the rest of the bed. And I'm pretty sure that goes for all of them. Oh yea......this bug is on the "Minecraft Pocket Edition" version 1.1.15........... it's also been on version from before

P.S- i don't know about the "Affects Version/s" since it's on pocket edition, and the MCPE version hasn't reached 1.1.4.51
