I can see resolution problem when I put the game on 4K TV by HDMI and duplicate screen mode.
Text on other text and it's not possible to save except the quick save ;)
Did you change the scaling?
my solution is to put the screen only on TV but the scaling doesn't work very well on duplicate screen, In the menu you can see text mixed together and I can't access to the save button. It's a detail, for now i found a way to save and play correctly on TV or PC :)
