Lighting/worldgenerator issue: black patches and dark spots appearing in the world
The bug
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.

How to reproduce
- Create a superflat world with the Overworld preset:
minecraft:bedrock,59*minecraft:stone,3*minecraft:dirt,minecraft:grass_block;minecraft:plains;village,biome_1,decoration,stronghold,mineshaft,lake,lava_lake,dungeon
- Fly around
→
You will find lakes with black patches and dark spots in a minute or two
Addendum
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.

this is odd i would mark this a duplicate but the dark patches are circular which is unlike a similar glitch that is being proccessed
Confirmed, even these dark spots can happen on places with torches.
Even you can see a secondary dark spot on the picture: the church has also a dark spot in spite of the torches...
However when I replace torches, these dark spots disappear.
Even monsters spawn on these dark places in spite of the torches!
Sure that fixed?
Yes, still looks fixed to me. Your issue is
MC-142134, I think.I don't think it's
MC-142134, because I didn't have any light sources like torches, beacons or lanterns near the black patches.
