Pick colors when non-focused windows are semitransparent via compositor

[Aster89]

I use picom to have non-focused windows semi transparent in i3.

The drawback is that this makes gpick totally ineffective, as in order to pick a color it needs to be in focus, so the other windows are semi-transparent, resulting in the wrong color being picked.

One way around this is to manually shut picom down, do the color picking via gpick, and then reactivate picom, but it's obviously a pain.

Is there a chance for gpick to be made more robust against such scenario?
