Hi,

I've noticed a small rendering error in okular, for certain PDFs, that other
PDF viewers (I tested Acrobat, Evince, GIMP's PDF render) don't exhibit.

I've generated a simple example. It is a plot created using the PyX python
graphing package. I will attach the relevant files. Zoom in and notice the
small stroke in the bottom-left corner of the triangle symbols, as if a pen
wasn't lifted from the page completely. These artifacts shouldn't appear.

Interestingly, if I run the PDF through pdftops --eps and then epstopdf to get
another PDF, the result doesn't have the artifacts. Seems to be something
peculiar to what PyX generates (though maybe other things, too).

Peace,
Brendon
