Yes, it's unfortunately normal at least in Acrobat 7 and 8, also in
Apple's PDF viewer (in Preview, Mail etc.).
In my experience esp. transparent (or flattened) elements show a fine
white border - but if you zoom in, it stays the same fine line or
sometimes disappeares. And it never shows in print.
