When flying around or using nether portals single chunks sometimes load extremely late to the point where I can land on top of the unloaded chunk and start taking damage. Instead of loading these chunks close to the player the game keeps loading chunks very far in the distance and the affected single chunks refuse to load until I wait in the area for a couple seconds. The non loaded chunks do eventually appear but it can take many seconds. There is no pattern to which chunks don't immediately load, it seems to be random.

In the image files attached you can see how it usually looks like. Every chunk in view distance is loaded properly and fast but one or more single chunks take forever to load in.

I noticed this happening since the 1.18 update (increased world depth) and it happens a little more frequent since the latest few smaller updates.
