UI Scaling?

[mdjenkins]

My issue is that I have a 4k monitor and there appears to be no way to upscale the UI.

I'm currently running windowed at 1600x1200. I've tried running full screen at many different resolutions to try and force a ghetto upscale. Anywhere I click while fullscreen causes the game to minimize and revert back to windowed.

All UI elements are a quarter of the size they should be. Stopping short at hooking up a lower dpi monitor; any ideas?
