My previous post of this issue was labelled as duplicate despite it being completely different from MC-166508 . So I have reposted. I ask you to look at this harder before grouping it with a vaguely similar issue. This is its own thing.
A server with 8 chunk render distance will only have 7 chunks displayed by the client, the outermost ring of chunks are not rendered despite them being complete by the client, you can see them render by using a mod that lets the clients vision move freely without moving serverside (free-cam), when viewed this way its apparent that the chunk has complete lighting and pallette, so why isn't it rendered? (even with client view distance at 32)
If this problem (intentional or not) were fixed, it would increase the view distance of every player on every server by 1 whole chunk, greatly improving quality of life for everyone.

As the reporter of MC-223350, this seems like quite a different issue.
This definitely isn't the FOV change bug, so it must be comparative to the world not rendering until the player moves their head after the world is first loaded. However, said issue is not present in 1.16.5, so this is likely a distinct bug, as this one is exclusively reported in 1.16.5.
How about MC-54545?
