The Issue

Whenever I enter into a new chunk (or a previously loaded chunk.) It causes freezing for a single frame.

How To Recreate

1.Create a world

2. F3 + G to show chunk grids

3. Walk into a new chunk / previously loaded chunk

I also notice that if I have my chunks turned down to 2 chunks then it gets alot better but its alot less aggressive of a freeze. 

I use optifine but I did make it to happen in vanilla 1.14.4
