Just encountered this bug in 1.16.3. I had to break the composter several times until a non-nitwit villager claimed it.
Can confirm it still happens as of 1.16.3
Hard to make a screenshot of a mob who doesn't render, don't'cha think?
Debug Screen provided; Although, I don't think any of that would help since the issue doesn't involve the debug info.
The F3 debug screen is not necessary if the bug is not performence-related.
Bug still present as of 1.16.2
Can confirm it happens on singleplayer worlds, too.
Confirmed; Pillagers pillaging my TPS
Bug is happening again in 1.14.4
This also applies to Kelp
I regret to inform you that this is only a visual glitch.
Makes the game unplayable on lower-end PCS, especially laptops that use an AMD CPU.
Still happens in 1.14.4 except now it permanently deadlocks the entire world in singleplayer and only a force-close can end it.
To me, frames drop to seconds per frame!
If I recall correctly it happens with certain shaders and AMD graphics cards, particularly when changing dimensions through portals.
