While mining underground (near bedrock level), rain appears when it's raining overground and the sound effects can be heard. Didn't happen on 20w16a, but you could hear the sound.
World was originally created on 20w16a and converted.

This is happening to me too. I updated a world from 20w16a to 20w17a and have seen the glitch at all Y levels. I tried reloading the chunks and that did nothing. I tried leaving the world and reloading it and that also did nothing. The glitch makes it look like small patches of rain are falling through however many blocks are above it.
Yeah I saw this, very strange.
