This occurs in the lobby on play.minehut.gg, not sure if this occurs elsewhere.
I also tested vanilla 1.9, to rule out server side issues.

1.9.2 protocol: https://streamable.com/0tilhl
1.9.4 protocol: https://streamable.com/0czbpl

Minehut has all 3 via plugins installed, you should use your native client version

Also minehut lobby is glitchy for me as well on any version with or without multiconnect, i just assumed it was probably their problem

I know, but the point is differing behavior from a vanilla 1.9 client

Any difference from a vanilla client is an issue.
This looks like an issue I've seen before, and fixed on the 1.8 branch. I'll test it now.

Yes, I confirmed it to be the same issue. This happens when chunks containing bed blocks are loaded with the 1.9.2 protocol or below. It might be severe enough to release a fix for before I release the 1.8 protocol. Try version 1.3.32
