If you have a high resolution screen change your resolution to exactly half. This will scale perfect 2:1 and not have this scaling issue. I do that on my laptop when working in CCP. If I leave it native and no scaling everything is very small but proportional but the windows scaling function is what causes problems. My laptop screen resolution is 3200x1800 and I change it to 1600x900 when using CCP and everything looks good.
