pdf not rendered to device pixels on high-dpi screen

Bug Description

If the global scaling factor is set to something different from 1 on a high-dpi screen, pdfs look blurry because they are rendered to UI units instead of device pixels. This renders the main advantage of higher-resolution screens (sharp vector fonts/graphics) useless for the moment.

org.gnome.desktop.interface.scaling-factor = 2
As I've heard the used setting for the scaling factor might change.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

Upstream bug is https://bugzilla.gnome.org/show_bug.cgi?id=723431 . Substantial work seems to have been done, but only some prerequisites are on master currently.
