While I was messing around in Minecraft I noticed a graphical glitch. If the player is 3rd person view and opens their innovatory and moves their cursor a bit off to the side this produces a graphical glitch. The player's head goes crazy glitching back and forth

Whats Suppose To Happen:
Player's head is suppose to stay still

What Actually Happens:
Player's head goes glitching back and forth
The player's head glitches more the cursor is away from the innovatory

Steps To Reproduce The Bug:
1. Player sets game into third person view (any)
2. Player opens innovatory
3. Cursor moves away from innovatory
4. Bug occurs

Note: Glitch is hard to see in screenshot but is occurring.
