If a player rotates in a single direction for a prolonged period of time, the precision of the "left" and "right" rotation decreases.

This can be caused by accidentally leaving a pen on a drawing tablet, causing the player to rapidly rotate in a single direction.

When placing down the pen on the tablet:

• Rotating for about 15 seconds has no effect
• Rotating about 20 seconds reduces the precision down to 0.5 of a degree
• Rotating 30 seconds or over reduces the precision to over 90 degrees, and prevents the player from moving and breaking blocks in the direction the player is facing.

This effect goes away as soon as the player returns to the main menu.

I have marked this as low priority, because it is unlikely players will rotate their heads in a single direction for days on end without exiting the game.
