Indeed. Different DPI settings. See below.

You got it wrong. The way it should work is that the parent document asks the
embedded objects to draw themselves with a given zoom (the same as itself, obviously !)
Well, this actually happens, but currently no object listens to that requests.

Now, why things break even at zoom == 100% is because KWord _zooms_ things even
at 100%, to respect the DPI settings (i.e. so that 100% is the size of a real A4/Letter paper
on the screen, not just 1 pt for 1 pixel). But since the embedded objects can't zoom, you
see a size difference.

So, I'm sorry to say, this bug is in all KOffice applications except KWord - but is
triggered by KWord's willingness to zoom things in order to respect the DPI value.
