When in a superflat world blocks render incorrectly
If you look at 1/3 of blocks on the edge of a chunk the blocks render as void. I think it is because of the new change where blocks that you aren't looking at don't render. Suggestion to fix: maybe make chunks that you aren't looking at that are next to the chunk that you are standing on render or maybe do that with 1 strip of blocks next to the chunk you are standing on.
