Evince (GTK+3) controls scale on Ubuntu 16.04 but not on Kubuntu 17.10

Distributor ID: Ubuntu
Description:    Ubuntu 17.10
Release:        17.10
Codename:       artful

Screen scale factor: 2.5
Force font DPI: 240

Unlike Qt5 applications, GTK+3 applications running on Kubuntu 17.10 do not scale their controls. Only font sizes are changed. This is not an issue in the Unity flavor of Ubuntu 16.04.

This isn't about kwin. Those decos come from the client.
(not really about kscreen either, but it's a bit closer)


There was an env set in startkde in the 5.12.beta but it caused other problems.

This should be fixed now.
