shift switcher has wrong stack of windows

Binary package hint: compiz

recentely the order used by shift switcher seem to a bit wonky

if you are on window 1, shft to 2, and stop, then cycle back, you will get:
window 2-> 1, 3, etc

but if i you start stop in 3, it will be:
window 3-> 2, 4,5....1

and not:
3->2,1,4,5,....last, as expected
