2. You can also choose to setup your Spire shortcut (right-click, select Properties) with Compatibility-tab settings under the "Change high DPI settings" section to Override with System settings:
3. Depending on how you setup your settings, you can change the look of Spire, both the object sizes and font sizes/clarity.

a. Fix-Blurry OFF, Override OFF
b. Fix-Blurry ON, Override OFF
c. Fix-Blurry OFF, Override ON
d. Fix-Blurry ON, Override ON
You can see when the Override is ON, the Fix-Blurry setting doesn't make too much of a difference, if any.
