Sky Glitching

I generated a testing world just for fun. At first, I decided to just start randomly teleporting, but when I teleported to these coordinates, the whole sky just seemed to be broken, like it was still in development at that height. Afterwards, I quickly deleted my world and left. I used my iPad to take those photo. It is the only evidence of this glitch. This glitch would've crashed this iPad. I was using the Windows 11 system to play this version. It was 1.20.
