I upgraded my 1920x1200 monitor to 3840x2160.
Windows OS scaling is set to 150%.
On this Windows 10 PC/monitor I am running a KStars client connecting to RPI server.
Pretty much all applications are scaled nicely and look good but KStars.
KStars/Ekos windows are just too large and don't look good.
They are totally usable though.

Is there any way to scale KStars windows/dialogs down some? Say to 75% ?

P.S. I ran a session tonight with all latest updates. Not a single problem.
