Running at a high resolution causes large portions of the screen to be UNCLICKABLE

At high resolutions (for instance, I tried 2560 x 1440), parts of the screen are unclickable. The unclickable portion becomes larger when the resolution is larger. At 2560 x 1440, the top third and right third of the screen are unclickable. So basically, I am unable to click certain parts of the menu interface unless I reduce the window's size, which sucks because I want to play it big and fullscreen.

This issue was also in the previous version, 1.3
