Weird Lines seem to randomly show up in my world. Its very inconsistent but I was able to take a few photos of it. Still can’t figure out how to reproduce this consistently.

Note: These steps may not work reliably its just what has worked for me.

Steps to Reproduce: 

1. Create a new world (Setting it to creative is fine)
2. Fly 50-100 blocks from spawn
3. Make a little platform and wall out of stone (Just to easily identify it)
4. Set time to sunset
5. Wait a few seconds (5-20)
6. Save and quit then log back in
7. Repeat steps 5 & 6

(If I can’t get it after a few tries I usually try a new world, don’t know if it has to do with seeds either)

Blocks that are clearest to see are Stone, Snow, and Packed Ice
