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!
