It really floods the journal log, and without setting a limit, this may cause
issues for some.
It seems upstream support for this has been landed:
https://bugreports.qt.io/browse/QTBUG-55167
I have tried the workaround, but this didn't to anything for me. Maybe my
distro (Arch) requires a different fix.
If this is isn't a KDE bug, sorry for the report.
