Thanks simonbcn.

I've checked with mine, and about the first three, I can confirm that it affects my reader too but not as distinguished as yours. I attached 1 pic for you to see for yourself. See in the upper right corner, the image icon (and the text "Images", faintly) still, although faintly, be seen.

I've downloaded testghost.pdf and try it on, and I do not experience anything going from 1st page to 2nd page.
2nd to 3rd I saw very faint ghosting, and took a pic but it is worse in pic, hardly anything.

You should return yours. I would do that if I were you.
