The recommended Windows Display resolution for the SystemWeaver Explorer client is 100%. 

If you do opt to use a different scaling setting, be sure that when you change the Windows Display setting while working in the client application, that you follow the Display Scale and layout instructions to sign out of Windows and back in to confirm a complete reset within the client. If you do not sign out, the application won't respond properly to the scaling changes. 

You can also try the Windows Advanced scaling setting "Fix scaling for apps" which will try to fix the application so it will look better the next time you open it, i.e., you will need to log out and back in to the application but will not have to log out of Windows.
