Tiny window when starting at native resolution

[MateusAuri]

I may be missing something, but when I try to start the game at 1920x1080x32 only a tiny top-left-most portion of the game is shown, while the rest of the screen displays whatever is running in the background in Windows.
When I start at a different resolution such as 1280x720x32 it goes proper fullscreen.

Maybe it has something to do with my computer being a 1366x768 laptop connected to a 1920x1080 TV via HDMI? Windows is properly displaying at 1080, though.
Oh, I'm using an Intel HD 5500 GPU by the way.

Anyway, it's a great fix, thanks!
