I was showing my friend all the new features of 1.6 when suddenly he got on a horse, my empty hand did not look right. When I had something in my hand it looked fine. It also does not look right when on the horse. (I cannot describe the look)

What I expected to happen was that my hand would be normal, not messed up.

What actually happened was that my hand was messed up. My friend claimed that his hand looked fine.

Steps to Reproduce:
1. Make a multiplayer server, log in, and go into creative mode.
2. Spawn horses and tame them (much easier for the process)
3. Ride horses and see if empty hands are messed up (it may just be the server host.)
