Caldron Not Cauldron

This might be a separate bug, but i see a similar bug report being marked as duplicate to this report. If your screen freezes a bit for every 5 seconds, it might be due to your internal storage has no more than 500ish mb left. The issue seems to be gone when i give more empty space to my internal storage. There is also another bug that causes massive amount of lag (screen freezes for quite a long time and you can't do anything) if you put Minecraft application to an external storage such as SD Card. In my case, i'm using an old and pretty slow SD Card though. I recommend putting the Minecraft app in your internal storage as it solved the issue for me.

This bug still occurs in 1.20.1

After updating to 1.19.61, the issue seems to be fixed for me.

I tried to reproduce it using the same world on local but everything works properly. I'm not sure about Realm, however. On Dedicated Server, the bug occurs with my world that has every experimental toggle enabled and is using a Scrpit API behavior pack. When I disable the behavior pack (moving the bp folder to somewhere else) the bug is gone and occurs again when I enable back the behavior pack. Another thing that I found during my testing is that if the world has Education Edition enabled, the bug won't go away even if I disable the behavior pack. And yes, I still can't reproduce the bug even using Education Edition on local.
