With high resolutions in Windows 10, windows will automatically adjust the DPI of the fonts in order to allow you to see these on the screen.
In most cases, this works, however in some specific applications, it can make the fonts all “blurry” and give you a headache when using the machine.

A fix for this is to enable the option “Disable display scaling on high DPI settings” within compatibility mode. This is accessed by right clicking on the shortcut and choosing “Properties”:
Once ticked and you run the application again, the scaling issue for the text is fixed. Unfortunately in this case, it makes some icons smaller (as you can tell by comparing the screenshots), however it is more usable and does not give you a headache!
