Hi mhcdesign_2014
It looks like your windows scale setting is >= 125% and Ai is scaling the UI to adapt to OS Scale settings, as in 17.1 it used to trigger at >=126% and many users complaint that Ai is not scaling at 125% scale which was case for most of the users. If you keep your windows scaling less than 125%, it will launch in 100% scaling.
