This happens when ever I execute any config from the config editor ingame, ( F6 )

On a side note, when Alt+Tabbing in and out the of game: When going back into the game I always need to wait for it to go fullscreen, alt tab out, then alt tab back in. Otherwise the game will sit frozen. This happens the same when clicking on the game from the taskbar.
