Hi,

okular (and kpdf) do render slow if I open a large pdf file with complex vector
data. If I zoom in, I get a blured rendering that is not improved sometimes.

Adobe Reader is faster and you can see how it renderes the different parts of
the pdf. Foxit reader using MS Windows is also faster.

See an example file (~ 2 MB) on
