Using non 1x1 scaling option for one display results in non accurate graphical representation of displays setup

It looks like the xfce4-settings display module doesn't handle scaling. When there is only one monitor setup - it's not that big of an issue, but consider multiple display setup, lets say I have 2 monitors. I setup with xrandr a 2x2 scale for one of the monitors. That scale setting is not reflected in the xfce4-settings display module - so the graphical representation of thix 2x2 scaled display is 2 times too small - it doesn't occupy as much space as it should.

Look at the attached screenshot. The monitor that is at the very top, in reality is immediately on top of the bottom one. So if I move the mouse cursor, there is no gap really - but xfce4-settings display module makes it look like there is a gap.

when I try to align those monitors to be snapped together, one on top of another - in reality they overlap.

It took me awhile to figure out what's happening here, but finally it makes sense.

If my explanation isn't really understandable, I apologise, please do tell me and I will try to explain it better.
