If you can share what is going on here with w, h, display_w, display_h would be great:

Thanks for opening an issue ticket .

w and h are equal to display_w and display_h, respectively, meaning the scale turns out to be 1.0.
All of them correspond to screen pixels, meaning w and h are twice larger than they should be on my system.
