More than year I am trying to resolve the following issue. My laptop has screen resolution 1920*1080 and I use Windows with setting 125% display scale in all applications. Wolfram Mathematica 12 works perfectly with option "screen resolution compatibility" and all the elements of interface are fine. However, it it almost impossible to use WM 13 because the application window and all elements of interface are huge. It seems that WM picks up 125% scaling from the global display settings in Windows.

What should I do to keep WM using 100% scale in order to make the interface elements normal sized instead of huge?
