I concur with the above – to give some more details on what is being describe above re location of the text if someone wants to go down a very deep rabbithole. The effect being described is called sub pixel rendering. Typically this is a left to right change thing. 
What I recommend is standardizing screen size and position – see ActivatePosition
Activate Commands (bostonsoftwaresystems.com)  Which really is a good thing in general because of convenience!
 
Even working with terminal emulators and stream connections I set screen size/position so that my development tools and the application land where I want them to help me toggle between one or the other. You’d be shocked how simple things like that improve productivity!
