In previous versions of Minecraft it had a visual effect when running (the camera moves away a little), now it is not thereIt will only be noticeable if you have the paper doll activated and in creative when destroying blocks you will notice that it does not do so Too fast as in previous versions.

PD:If you find an error in the spelling it is because I am using a translator, greetings Mojang team from Nicaragua 🇳🇮 ✌️

PD (again): the video shown will be in creative, it will show the block destruction time and you will be able to notice in a part of the fragment the visual bug when running looking at the paper doll.
