Nearby recently-spawned projectiles don't render when the game is frozen
Step 1
Run /tick freeze and then run /summon experience_bottle ~ ~ ~
As you can see as long you are within ~4 or 5 blocks of the bottle while the game is frozen, it is not rendered. If you move more than 5 blocks or the game is "running normally" (tick unfreeze), it will render properly.
