Depending on your position Chunks appear and disapear

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:
