Nether Pauses entities for few seconds

We all know nether is dangerous in anyway, but this update makes me dont want to go to the nether until it will be fixed.. I first incountered this when i was destroying Netheracks, i have efficiency 4 and i hold it to clear the Area near my portal and it happened that the blocks are disappearing no particles no sound, i stop mining and 2-3secs later the particles, sound and Drops of it appear. It is so weird when i realized that this is a bug, when i was Riding a Strider and a ghast fired at me and it happened that the strider stopped moving the ghast stopped too even its fireball is just floating in front of me, but still i can move my camera view and if im in land i still can walk and do my stuff, but the nether entities paused for few seconds and unpause and paused again and unpause it just happened everytime.
