Constantly disconnected from servers in 1.13 pre 1 and pre 2

Several people were on this server with me, all experiencing this bug. We all get randomly disconnected every few minutes with errors such as "Internal Exception: io.netty.handler.codec.DecoderException: Badly compressed packet - size of 9048150 is larger than protocol maximum".

We had the same errors in 1.13 pre 1, and it really breaks immersion.
