When you log out on fullscreen nothing happens but when you log on it goes black screen
For it to log on after a minute of maybe lag but we left it for 24 hours and it did nothing
It should have gone to the title screen

It stayed black screen for all 24 hours
Well we gave up

Steps to Reproduce:
1. Open minecraft (any version)
2. Go to options and click fullscreen on
3. go out and click quit game
4. Try log back in but you get black screen
