The bug
Blocks are lit up with jagged, non-smooth edges, even when smooth lighting is set to true. This only happens between light levels 0 and 1.

This seems to only occur when the block light level is transitioning from 1 -> 0 and the sky light level is 0. When sky light level is higher, the transition is smooth.

Doesn't just affect snow, it affects all blocks.
Best tested in a cave world.
