Missing title bar and window frame in windowed mode
Players who play the game in windowed mode and select their monitor's native resolution as their resolution choice may notice that the title bar and window frame are not visible any longer, which will look a lot like fullscreen mode. The major difference between this mode and fullscreen mode is that the game window will not minimize when you change focus to another application or your desktop.
If you would like your mouse cursor to leave the playable area while in this mode, you can toggle the Cage Cursor option in the Game Options menu.
If you would like to see the window title and frame, you'll need to lower the resolution to something smaller than your monitor's native resolution.
We apologize for any inconvenience caused by this - there is currently not a way to play with a maximized window that has a title bar and frame.
