Main menu glitch

I don’t know if call it as bug or glitch, it won’t injure the gameplay or something, but is a weird behavior

Take a look:

  1. Open the game normally
  2. Choose a server
  3. Press scape when you see the “Connecting”
  4. ???
  5. Profit!

It showns a black screen, then crashed

Hmm, I will look at this later. See if I can confirm this works.
EDIT: This works, I also see a monsters shadow in the background.
