4k resolution scaling bug

[Dafoof]

When trying to set the resolution to 3840x2160 (my native screen resolution), the scaling goes crazy and I can only see what seems to be the top left quarter of the game (as if resolution was somehow still 1920x1080, but the game would be displayed in 4k). Restarting the game does not help either, the only way to get a normal display back was to switch back to 2k.

Just saw mention of the high DPI settings for the executable, in other posts, this did the trick!
