CSS filters causing image distortions

[fractalawareness]

Just take a look at https://url-to-pdf-api.herokuapp.com/api/render?url=http://bennettfeely.com/filters&waitFor=1000

The first image (no css) has smooth lines but other images have glitches because of the filters applied to them. If you open the source in Chrome it has no such distortions.

This issue belongs to https://github.com/GoogleChrome/puppeteer or even Google Chrome, which is the underlying piece doing the rendering.
