Someone discovered that you can connect to (at least) 2 servers at the same time if you are quick and you have a bit of lag (~300ms)
Here's how to reproduce :
Start connecting to a server
Cancel the connection quickly
Connect to another server
If it happens to work (based on your lag mainly), you're connected to both servers. You can see both chat, both scoreboards, ... The thing is you will send your inputs to the first server while your client think you're on the second one.
If you're on the same coordinates, you will see the second server map, move like you're on this server, eventually fly if you're on creative but the game will send your movement to the first server, which has a totally different map, making you able to glitch through blocks and fly over them.

PS: I'm sorry if my explanation isn't clear, my english is not great and it's a bit hard to explain 😞

Confirmed for
1.8.4 (Client) You can also just spam the "Join server" and "Cancel" buttons because they overlap at some point The launcher might eventuall freeze when you join a plugin server and use this bug, because after leaving the server you get all the error messages that were generated while you were on the server
