I put f5 two times to see my skin so then I zoomed in all the way that all I could see was my head and pressed the Inventory button then I went to survival Inventory and bam! My head was Derping and twitching!!!

*What I expected to happen was
For me to see my skin's head

*What actually happened was
My head twitching and glitching...

Steps to Reproduce:
1. Press f5 2 or one time 2 times is recommended
2. Get closer to your head until its the only thing you can see
3. Press survival inventory (on creative) enjoy the Derpiness!

I made a video about it here's the Link: http://www.youtube.com/watch?v=_9h-_1sxY64
