I imagine that you are getting tired of me. Oh well, here is another.
When you have scale mode set to 150%, there is some clipping on the menu height. It also appears that the title bar height is short too because the minimize/maximize buttons and close button height overlap the title bar height.
I do not see these problems on 100% or 125%. Both of those look great.
Perhaps if I was testing this on a true 4K device it would look better. But with me using Windows 7 1920×1080 I imagine that squeezing 144 DPI (150%) might be stretching it some and causing some distortion.
