When running the game on 4K screen cursor is either boxed in top left 1/4 of the screen and transposing to rest of the screen (in Fullscreen and Windowed mode) or displayed on 1/4 of the screen in Borderless Windowed.
This makes this game unplayable for me.
Examples below:
Fullscreen as you can see cursor is in top left while selecting Options menu section.
Borderless Windowed this shows just over 50% of the screen area. And again cursor is in 2 places.
