When I killed a pig it died and it slid when it died instead of disappearing

When I built the nether portal the sounds the nether portal makes on normal minecraft aren't there and even the is no area where it is like a revan in the nether

When I hover over a item/block or anything the box where the name is said blinks instead of saying it and fading away or disapearing

When I type and I would press backspace the letters look like they come back super quickly and disappear as normal
