Hi, I'm hoping this will already be fixed in update 9 by the cleanup improvements I did to the canvas implementation a few weeks ago, but just to be on the safe side, I'd like to test it. Is there an example or app I could try to verify that? (I'd prefer to get a complete example rather than recreating it based on the posted code segment to ensure that it is covering the right cases)
