Bug detailed description:
-------------------------
With the newest commit (for-linus)76be97c1fc945db08aae1f1b746012662d643e97, I found that if we firstly change xrandr's panning from "1024x600" to "2048x2048",then "2048x2048" to "1024x600", the next change of scale will be fail if you move mouse for a little time.But that will not happen, if we change scale before exchanging panning as said above.

Reproduce steps:
----------------
1.xinit&
2.gnome-session&
3.xrandr --output LVDS --panning 2048x2048
4.xrandr --output LVDS --panning 1024x600
5.xrandr --output LVDS --scale 0.5x1
6.moving mouse
