In this case, the application I'm working on does not specify any
styling of the tab bar, but switching from Qt 4 to Qt 5 ruined the
default style on Mac (see the images attached to my first message in
the thread).
I'm actually working around a bug in Qt here (I believe it is
https://bugreports.qt.io/browse/QTBUG-74689).

I also expected that adding one single style sheet instruction would
add it to the default style.
Instead, the default style was mostly disrupted.
I would consider this a bug as well (hoping it is not intentional, in
which case I would consider it a bad design choice).
I don't know if this has already been reported.

I don't expect any problems in this case.
It is the only stylesheet used in the application and it has a very
specific purpose: should Qt's behaviour change in this respect, I have
only these few lines to possibly adapt.
Anyway, I would be grateful if you could point me to a better way of doing it.

Best wishes.
