Please fix this its unplayable!
Alexandre Auclin the problem is maybe due to changes in the options.txt file. In 1.12 there was numeral id for keyboard options and now it is the name of the key. Additionnaly, the capsLock key cannot be used now.
Still happening in 18w22b
Obviously the player is turned only 20 times a second, so that can look like lag. However if you try this on older snapshots, like just when the facing entity was introduced, you will notice less lag from the view. So the problem came after.
The entity rotation is also even worse with zombies, skeletons... and every entity that can move its head vertically.
Still persisting in 18w05a.
