"Chunk Spaz"

Everytime I rejoin a world all the blocks go everywhere and anywhere! This also happened on realms. I tried reloading the chucks by doing F3 + A but this only made it worse! The only way to fix this is by closing minecraft and reopening it. This is VERY annoying when I'm switching minigames on realms. I have pictures. And I was not the only one who saw this. I had 1, only 1, friend who had to deal with this too. But no one else said this happened. PLEASE FIX THIS!!! This is one of the more annoying glitchs with this update.
