Yes, I have heard about this problem before. Those hidden
objects are usually printer margins, crop marks etc. which are
part of the PDF, but not inside the PDF's MediaBox.

I now changed the pdf2swf code so that objects whose bounding box is
completely outside the page are not drawn anymore.
This will, of course, not work for objects which are partly inside the
page (like the red object in your example). Does this case actually
occur, btw.?
