 Description   

Issue: Movement corrections sent to the client are not smoothed out

Observed Result: The client will replay its inputs and teleport the player to the final position after replay.

This teleporting is especially noticeable on higher latencies, when attempting to correct movement for something like knockback during combat (as shown in https://streamable.com/3miw7w)

This is reproducible on a BDS server while having high latency - "set server-authoritative-movement" to "server-auth-with-rewind", and "correct-player-movement" to true, use some sort of tool (such as clumsy or a VPN) to get high latency to the BDS server, and then taking knockback (to a mob or a player). The same behavior will show as in the last video (see https://streamable.com/be72t0)

It seems that corrections are now smoothed in .81

Resolving temporarily as Awaiting Response. Is this still an issue in the latest version of the game (1.20.1)?
