Display/resolution issues have been reported on Windows 8.1 and Windows 10, especially on large resolutions or 4K screens. See for instance the screenshot "weirddisplay.png" below.
Several users have found a "fix" for this.
A user 'fixed' it via the compatibility troubleshooter. See the screenshots:
Another one seems to have used another setting. See the screenshots:
I also have this problem. I am using WIN10 instead of WIN7. Not sure it cause by WIN10 O/S. I use compatibility troubleshooter. Did not work the first time. Third time before it work properly.
I have re-edited the original post, the screenshots should display well now.
