Depending on my position chunks get invisible and turn back to normal.
Sometimes there are many "buggy" chunks in one area, as you can see in the screenshots.
I couldnt figure out why this happens and why it changes when i move.
I tried f3-a, block updateing and reentering the world, but it didnt help.
I hope you can fix this!

Here are the screenshots:

EDIT: Sorry! someone was faster, delete this issue.
