XMir physical monitor layout sometimes disagrees with that shown in xrandr/control-center.

On a few occasions I have placed one monitor left-of or above/below the other using xrandr/control-center. And while the tool always shows success in making the outputs adjacent, sometimes the physical display buffers are rendered overlapping at the same location (0,0) instead. Making a second change in xrandr/control-center seems to correct it, and finally what I see is what was configured.
