Comment # 10 on bug 1123131 from Tom���� Chv��tal

Now the font rendering seems borked in openQA:

https://openqa.opensuse.org/tests/841865#step/ooffice/4

To quote from LO irc:
[09:44:22] <jmux> scarabeus: some Qt bug or bugfix AFAIK. Works ok with qt 5.9,
but breaks with qt 5.11.
[09:44:59] <jmux> Fun fact: the rendering is actually done using cairo and not
qt
