Full screen on high res display

[NiNo]

I tried krp beta12b on a new PC with 2880x1620 display resolution and got problems at start-up:  krp started in full screen mode, but picture was shifted to the right (wide black band at left edge) and with low resolution.  The game menu was out of bounds -- not visible and not possible to reach.   I then edited .ini-file to use window-mode and restarted krp.  Window-mode works OK, also at 1880x1620.
