If you fly around in a 22w16a world, especially if teleporting, some chunks begin to get mixed up, resulting on "fake" sections of chunks appearing, like a chunk with parts of spruce trees in a Forest biome, these are visual bugs so the shape of the terrain is not affected, but it looks very confusing, like in Spectator mode if you were to try to go back into creative mode within a cave, you'd suddenly be inside Deepslate, since the cave isn't actually there.

World updates seem to also affect it, having it cycle through different parts due to Sculk Sensor updates or Lava flowing, using /setblock and even spawning in a 22w16a world also causes this.

I genuinely thought it was an issue with my hardware possibly running out of storage, but this issue didn't occur in 22w13a, and only began when I loaded the world again in 22w16a, I have a short clip of this bug which I wanted to add but it just goes over the space limit on this site, and during that clip the game crashed as I was showing the bug.

I do have several screenshots which when together like a slideshow sort of visualize this bug in action as well as the crash log from the MC launcher possibly caused by this issue.

22w16b does not fix this either, as one of the screenshots below of a Wooded Badlands is what I was greeted by when spawning in a new 22w16b world!
