Jumping letters from example pdf

From time to time I get PDFs which look strange with okular (which uses poppler), but not with Adobe Reader. In this case the problems are "jumping letters". Please see
http://www.ee.technion.ac.il/~rmeir/Publications/MeiRae03.pdf for an example.

Screenshot from acroread on 600%

I don't think, that it is really a rendering problem. I've made a screenshot from acroread at zoom of 600%: You can see, that all characters with curves at the bottom are not sitting on the base line, they are about 2 - 3 pixels lower. This produces the "jumping" effect. So it's a font problem (embedded in the PDF!). The only difference between poppler and acrobat is the different font rasterizer and that acrobat always renders the font again when You zoom it!
