A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Even in windows 10, the DPI settings do not fully take effect until you sign out of your profile and sign back in.
I tested without signing out, and the problem does not occur. Excel also does not look very sharp until you sign out and sign back in. I retested after signing out and the problem still happens.
You need to sign out in order to reproduce the trouble. please try this.
It might also be worth it for you to try it out on a machine with an nvidia video card. Both machines I have are using them... and the problem is obviously somehow related to video settings.
