Might be OS screen display settings doing this.

Control Panel, Display and experiment with different screensize/resolutions and check the display with each one.

Older program and some of the newer display sizes may just be having a catfight...

Worth a try and you can always just change to known working setting just when you want to use this program, then change back for everything else. Ex: Things may look klunky at an "older' setting like 800X640, but it may display the stuff visible.
