Thanks for the reply. It just seems counter-intuitive that canvas area should matter so much when the drawing logic is essentially the same. We are creating the same number of objects, just on a larger canvas and with different (X,Y) coordinates. Thus, the creation speed of the canvas itself (in memory, before flipping) should be roughly equivalent, right? The slow-down is simply from having to re-render the larger canvas? I'll dig more, of course, but quick insight from those in the know around here is always appreciated.
