Does not work in pharo 3.0 either on my ubuntu system. My VM is dated 13/03/2013. I don't think I'm using a particularly old one.

Probably because you should cache the result you get and not redraw it all the time. You should control when you want to redraw it. So your Morph should hold a form or something like that.

Thanks for the attachments I will take a look at them. The time it takes to render the fractal is not the problem. But after that, if I want to drag or resize the window the fractal has been draw into, the sluggish begins. Even with the fast dragging option checked.
