Best guess right now is that optimization does something bad when ceil() is called twice on a very large dbl-precision number, which results in a zero (empty) redraw area. Without the removal of the redundant ceil & floor functions, no expose events would be delivered to the canvas in an optimized build during drags (and maybe more).
