I was on a server and this happens when I am in a specific area. Was this on a server? Try moving away from that area.
This isn't a technical support issue though :/ its a glitch/bug :/
Well I'm sure they at least move about when normal, but nevermind.
Assuming this person hasn't found a way to fix this yet, have you tried reloading the world or redownloading minecraft?
But if you have that's ok.
Also this was on the world building height
It's happened to me in 1.8 before.
I guess this should be fixed as it isn't quite a full block
This has happened to me. I'm not sure if it's fixed by now as it only happened yesterday before I logged off, so...yea!
Oh, sorry! I forgot to do a search.
Maybe try relogging a good few times? Try checking to see what might cause a problem. If you have major problems, maybe redownload Minecraft?
You need a lot more information for anyone to help you out.
Yeah, sometimes it even happens with players
Jukeboxes are slightly more weird, They sound kind of goes high and low at different times. Weirdly it only happens on servers!
Yes but it has been reported and needs fixing. The problem isn't with the skin or the Skindex website, its the security question for uploading a skin. READ IT CAREFULLY, DOOFUS.
