Three times slower in layout, and two thirds of that was a stacked child redrawing twice a frame rather than the arithmetic. The counters are what found it, once they could say "another layer" at all. The performance table is rewritten around the fixed-point commits and in milliseconds a frame, since the fixture it used has changed and the old instruction counts cannot be compared across it.
