Created attachment 103017 [details] PDF with wrong scaling-factor If you choose a scaling-factor (Systemsettings->Hardware->Display & Monitor->scale display) which differ from 1, the font rendering fails and the displayed pdfs look very poor. It only works well with the scaling factor 1, every other crashes the font-rendering. I have a 3K Monitor(2880*1680).
