UHD screen issues

I just wanted to do the smallest of image edits and not be here write up bugs  that should have long ago been detected and resolved!!!

Is there a magic fix for this?

Then I have this mouse cursor that appears in Draw and X10 the size it should be.

And a save dialogue that's near in-proportion to that hint text.

And the only reason I updated to X8 form X7 was because I was told it correctly supported UHD monitors.

Are there settings I'm missing here? Is the program picking up monitor details from the second monitor? WTF?
