Not invalid, this is a new issue caused by MC-236619 (kind of). Attached some screenshot on the seed: -8330603083619589917.

Seems like weather doesn't work correctly with 3D biomes.

I don't think this should be Invalid, as jungles are not suppose to have snow below y=256. So I am pretty sure this is a bug, not a feature request.

ampolive

Can confirm.

@unknown, they are not supposed to have snow above Y=256 up to Y=540 or something.
Either way, I'd agree that this is a bug.

Can confirm. There is also an issue in areas where it does not rain but is supposed to wherein particles generate on the floor with no raindrops and vice versa. I even found a border between rain and no rain in the same biome, but could not locate any major value change that indicates what causes this.

I also cannot reproduce appears fixed in 21w40a

I recommend to still not close this issue, this might be still happening in cave biomes, and also could have issues with custom 3d biomes.

Not fixed. It still rains in dry biomes when there is a cave biome beneath.

In the above example, it rains in the savanna because there is a dripstone cave below.

whoops sorry

This was fixed in 21w41a (for real this time)

Moesh

Is this still an issue in the latest snapshot?

syarumi

Not quite fixed, still happens with cave biomes in default worlds. As you can see on the images, there's still some quirkiness when a dripstone cave is exposed to the sky, making the weather incorrect in snowy plains, but if blocks are placed on this biome the weather remains correct again. Not to mention this could mess up with custom biomes on the sky.

The expected here would be the weather to change exactly at the biome edge, or else give priority to the highest biome.
