Graphical (?) glitch

Pretty much that. Happens mostly on multiplayer servers and will not go away unless I either restart minecraft, or sometimes it will persist for as long as 15 minutes.

was made for friends to see my problem, as a joke partly. But, it is very annoying. Would like to know the cause, whether its the game or my computer.
