      The bug

      End gateways and portals appear to have major effects on framerate when there is a large group of them, unlike any other block I'm aware of, and it's not just from the dual beam animation.

      How to reproduce

      1. Run
        /fill ~4 ~10 ~4 ~-4 ~2 ~-4 minecraft:end_gateway
        

        →  Causes a very significant frame drop.

      2. Now, try to run
        /fill ~4 ~100 ~4 ~-4 ~2 ~-4 minecraft:end_gateway
        

        →  It causes complete unplayability.
