Created attachment 157812 [details] PDF which displays rendering artifacts at 150% zoom SUMMARY Okular displays rendering artifacts when one opens a PDF and zooms in a bit. Apparently this is caused by the Splash backend in Poppler's Qt backend. Enabling the Cairo backend should fix this. STEPS TO REPRODUCE 1. Download the attachment 2. Open specimen.pdf in Evince and Okular OBSERVED RESULT Evince renders the text as expected, all characters are on the same baseline. In Okular, the characters jump up and down. EXPECTED RESULT All characters are on the same baseline.
