After converting some pdf documents to svg images by pdftocairo all web browsers (at least Firefox 56.0, Safari 11.0, Chrome 61.0.3163.100 in MAC OSX) show artifacts on images. To reproduce the issue make the following steps:

convert the attached pdf to SVG: pdftocairo -svg -f 1 -l 1 err-doc-5.pdf err-doc-5.svg
open the SVG image by any mentioned web browser and check how it looks. It expects no any artifacts on the image but it contains black rectangles. Researching the SVG content showed that these elements have the following structure:

This issue has been tested with latest poppler versions 0.60 and 0.60.1. Previous versions of pdftocairo also contain this problem.
