[Client]Mac Client Resolution problem

When I switch from external monitor to mac's built-in monitor or the other way around, the in-game resolution wouldn't fit the new monitor, and showing only the upper half of the game window on the lower half of the monitor, but the mouse clicks were not affected(making clicks and graphics not match). After struggling to find the right area to click and set to what resolution suits the new monitor, I am able to play the game, but it would happen again when I change the monitor. The bug has been around for at least 3 weeks. See link for some screen shots. http://imgur.com/a/Wvv3n
