The game freezes for a few seconds before redirected/respawning or being teleported

Hi Mojang this bugs annoys me alot please fix this...
Sometimes when i play the game for a long time, when i do something that is related to "teleporting" my game freezes on the "dirt screen" for a few seconds before i completely respawn/teleport, which is very annoying especially when am rushing
Any workaround or ways to fix this?
What i should expect was:
Well it should work smoothly without hangs or lags etc
What i instead expected was:
This bug, where the game lags when i do something related to "redirecting" like quitting from singleplayer to title screen
How to reproduce the bug:
1.Open the game and play it for a long time or after opening it sleep your computer and leave it for a long period of time then put your attention to the game
2.Now go to multiplayer and do something like going to an another server
3.See?
