Some notes if controlling Optifine
Disable Fast Render
Portals can render wrongly if shaders are inactive. If you are in that circumstance, please join the world again!
Don’t toggle the Render Region feature if staying next to a portal!
Switch off Smooth World because it will disable mobs’ AI if they are far away.
