High resolution?

Hi everybody

I just bought a new laptop and downloaded Scrivener again. It used to work perfectly in my old pc (15.6’’) but in my new laptop (14’’) looks fuzzy, as if it had low resolution or sth - see image below. Any idea how to fix that? Is quite annoying to work in such condition!
Btw my Scrivener is 1.9.7.0.

Thanks for the help!
