There seems to a Bedrock Realms chunk generation glitch. I will attach a video here to showcase the issue.

In this video, I am in a Minecraft Bedrock Realm that was created in 2021, right when the first part of the Caves & Cliffs update came out. I am standing in a chunk that was loaded during that update. However, in the video, you can see that it almost looks like the game is trying to load in new chunks on top of previously loaded chunks. This Realm has gone through many updates and has not had this issue, until 1.21.22. It seems to be mostly a visual bug, because when I walk towards these generation glitches, they go away, and it restores the old chunk. It mostly seems to be prominent when loading old chunks (chunks created before 1.21.22) as opposed to new chunks (chunks created after 1.21.22), and mostly happens when I am flying my elytra (aka, loading chunks quickly).

I know this is a Realm-related issue because I downloaded the Realm file as a world download to see is the issue persisted there, and it did not. What is most concerning about this issue is that I haven't seen anyone else have this issue, and I don't want this bug to somehow corrupt my Realm/world.
