There is a pretty rarely noticeable bug that depends on ping i think, it can be done between any dimension and survival. link to a video: https://drive.google.com/file/d/1SFHzwYl9_Gc1MPTLWimlV4ntm4YZEd0C/view?usp=sharing
in this bug while transferring from a dimension to another the background changes before the player does, where if you were inside of a jungle in survival you can switch to pvp dimension and get 1-3 seconds of free light hacks, and screenshot what you find and later come back and get it. i think this is something that can be fixed since it depends on player ping i believe, and forcing it so that the background only changes after player had successfully changed dimension. other then that the bug is pretty straight forward and i replicated it multiple times in a row.
