Debug hitboxes cause client-side lag

I think this is new in the 1.20 snapshots, I play with hitboxes on a lot and have never noticed such a drop in frames.

I was chopping down some bamboo and I turned on debug hitboxes (F3+B) and my frames went from 60 with Vsync to like 20-30. Even with few entities on the screen it still considerably drops the framerate.

Steps to reproduce

1. Go somewhere with a lot of entities
2. Turn on debug hitboxes
