Reproduced in a minimal testcase and reported upstream as https://bugreports.qt.io/browse/QTBUG-71238

Comment 4 Matej Mrenica 2018-11-08 15:14:25 UTC

Still happens with Qt5.12-beta4

Comment 5 Rainer Finke 2018-11-22 21:19:48 UTC

And still an issue in Qt 5.12 RC1...

There's a comment on the fix:

I guess it's up to distros to patch that.
