The snowy Kingdom superflat biome spawn abnormal. The snow on y=64, the grassblock on y=-1. This is probably caused by MC-214951.

Since the height limit was changed in 21w06a, the water world preset has sea level below height 62, making the ocean monuments appear above the sea and with a large area of water around it.

Dupe of MC-214951
Duplicate of MC-214951.
Since MC-214951 was regarding the dark horizon and has been fixed, please do not mark this as a duplicate. Also, please do not mark as a feature request, because ores used to generate normally for superflat, they just don't now, which is a bug. Thank you!
Since deepslate has not been added to superflat at all, it spawns you in negative coordinates. This, for some superflat presets such as Classic Flat, is not a problem. However, it breaks many presets such as Overworld, Snowy Kingdom, and Desert. This causes the ores to fail to generate being that the superflat presets have not been updated to generate deepslate and ores do not generate in stone below y=0.
Would MC-214951 happen to describe your issue? If not, please attach some additional screenshots or videos of this problem occurring whilst the F3 debug screen is enabled. Thanks ![]()

In addition, many of the presets should have an additional 64 layers added to them so they are consistent with their default counterparts. Details are in the linked bug
MC-215423.I think it odd that it was resolved as a duplicate. This is more of a visual issue rather than world gen, as Classic Flat has always generated at the very bottom of the world.
Can confirm in 21w07a.
May I suggest for the title to include 'horizon' or 'black horizon'?
I was just about to report the issue, as I didn't find this ticket before, and was pointed here by a helper on the discord!
fixed in 21w11a
Can confirm that this issue has been fixed in 21w11a. You are spawned at negative coordinates however, no "dark horizon" can be seen.
Just an question, this was fixed, but why is this not in the changelog?
Jamie Bucarey It was probably fixed as a result of another bug being fixed / Mojang wasn't aware of the bug or the fact that it was fixed.
