Would Athens be faster in this case ? I did not try because Athens is using Morphic anyway so it should be same if not worse.
Athens may be faster because only the final drawaing is done on the morph, not your intermediate drawing, if I understand correctly, so worth trying.
Why do you need AlphaImageMorph? You want to adjust the overall transparency of your morph canvas? In that case, I think it will be always slow because software rendered.
Note: for PNG file coming with alpha transparency, you don't need AlphaImageMorph to get the bitmap rendered with its transparency.
