Ok so 6 months ago before I got this bug it had no lines after some days I got the bug and it affects the multiplayer and single player and if u zoom closely on the hand you will see little dots lines on it but with the character its like black lines if you zoom closer you can see that it has dots but mostly black lines this is not like MC-1794 that is a block bug mine is the character. It affects from 1.0 to latest the lower versions are the least affected like the lower versions dont have the hand dots lines.
