Fix Version/s: Minecraft 19w14a
Starting with snapshot 19w02a, there are pitch black patches and dark spots quite commonly in the world, mostly in the plains biome. I haven't seen these in any other 1.14 snapshot that includes the new lighting system introduced in 18w43a.
I could imagine that some of the new code has been reverted to improve performance.
- Create a superflat world with the Overworld preset:
- Fly around
→ You will find lakes with black patches and dark spots in a minute or two
Now that I dug deeper into it, I think this is just a reappearance of
MC-29490 which got fixed in 18w06a when the new world generator has been introduced.
