I have Wheat Seeds in my right hand, and Bone Meal in my left hand, which is my off-hand. I keep pressing my right click button to use those items. As a result, if there is nothing on a Farmland, the Wheat Seeds are planted, and Bone Meal make it grown instantly. Clicking my left button, I can take wheat.

However, there is something wrong in the texture of the Farmland. I did NOT keep pressing my right button, so the Farmland shouldn't be cracked, but it is.
