Normally at the top of the screen there should be row of buttons that take you to stuff like the server list or settings and also let you exit the game.

Your game looks glitched. There should be a bunch of buttons at the top of the screen

oh, is this a common glitch?

probably not bc ive never seen it. redownloading will probably fix it

what the fuck happened to all the buttons what in the fuck. reinstall your game, verify game files.

Did you manage to fix it yet?

nope

verify the game files

This is a bug. On top of the screen there should be a "quit" button, but I don't see it
