That's not going to be easy. GTK4 has gotten HiDPI support on Windows recently, and I think it barely made it in time for last GTK3 release, but we're using GTK2, which is not really developed anymore, so HiDPI support would have to be backported, which may not even be possible. I'm not sure GTK2 even has HiDPI support on Unix (X11/Wayland).
