I also see these warnings but they do not seem to cause any misbehavior.

I have none, unfortunately.

I don't see this specific warning. Only a lot of
/usr/include/qt5/QtCore/qdatastream.h:346:21: warning: ‘QDataStream&
QDataStream::operator>>(quint32&)’ redeclared without dllimport attribute after
being referenced with dll linkage
inline QDataStream &QDataStream::operator>>(quint32 &i)
and some hunspell warnings about deprecated declarations.
