Some snow blocks persist/refuse to melt

Description

Snow blocks have a somewhat regular frequency to simply refuse to melt (be purged on chunk load during high temperatures). The cause of the issue seems irregular - initially I had though it only happens to snow piles that gathered under tree leaves or vine "blocks", but there are exceptions to that as visible in the screenshots.

How to reproduce

1. Enter any standard-generated world
2. Simulate the passing of a winter season into spring/summer in a moderate climate
3. Travel through the world until the issue is visible (search the map for odd white pixels)

Screenshots

Screenshots were taken during summer, with in-game temperature around 25°C.

Snow blocks are not purged on chunk load. Instead, when a single snow block receives an update that it should melt, all adjacent blocks melt as well. In flat areas this can look like clearing all the snow in a chunk.

The snow in the screenshots will melt eventually, it just takes a while by virtue of it choosing a random block in the chunk to tick every, well, tick.

That doesn't change the fact that we are left with extremely awkward single blocks of snow in a 30°C weather during summer. Even if it's not a technical bug, it's still highly immersion-breaking.

Closing due to inactivity

[noelle-lavenza]

This issue still exists, why was it closed? It's inactive because devs haven't responded to it—which is understandable, because it's difficult to fix—not because of a lack of information.

Okay
