You need to add in the origin offset of the world's FormCanvas when you
draw upon it directly through its GrafPort, otherwise you are Blitting
your red rectangle starting at the origin of the Display, rather than the
origin of the Morphic window.
Should be something like:
port
copyFrom: buff boundingBox
in: buff
to: ((destRectangle origin) translateBy: self origin).
When I do that, the rectangle is always red, as I think you are expecting.

Thanks - that did the trick.
