I have JIT disabled and this had no effect. On pass 1, I change the colors before the canvas is displayed.
On pass 2, I change the colors (different colors as pass 1) again via the same method calls. One would think that it would render faster after this call since the same methods were called in pass 1, although the only difference this time is that the canvas is visible. Only after the 3rd pass it is much quicker. Seems like the performance may be related to the visibility status of the canvas. Any other recommendations. Thanks for your help.
