Has anyone had any luck using GtkD on Windows with a high-DPI display?

I could not figure out how to stop Windows from scaling the application, producing a blurry result.

I am using the latest GtkD (3.2.1) on Windows 10, with the Gtk runtime provided (3.18.3), compiling with the latest version of DMD (2.069.2), on a display with a resolution of 2560x1600 (with a scale factor of 2).

The program I compiled was the sample "hello.d" given in the GtkD package. It looks perfect, except for the scaling.

(Obviously, the best thing would be to enable so-called per-monitor-DPI awareness. Not sure if the Gtk port provided can even do this, though....)

Any ideas?
