If I decided to pick up on this it's because I had had enough of it that about none of the Medium/Semibold fonts I use in my GUIs were stable (i.e. always "evolved" into either Bold or Normal).

Hmmm, yes and no. Qt4 is affected too, but in a different way.

This doesn't have anything to do with rendering. I'm not touching that. It's got to do with getting the proper QFont :

QFont font = QFontDialog::getFont(&ok, QFont(), this, "Select Font", options);
QFont font2 = QFont(font.family(), font.pointSize(), font.weight(), font.italic());
QFont font3 = QFontDialog::getFont(&ok, font2, this, "Select Font", options);

the second dialog can give a different font than the one selected in the 1st and indeed font3==font2!=font . Good test fonts are the Avenir Next and Helvetica Neue families (system fonts on OS X, the latter then new UI default), or even the Segoe UI family that comes with all MS Windows machines.


Anyway, I'm not going to insist it has to go into 5.4, but I'm not going to go out of my way to prepare and test the patches against software I'm not even planning to build without proper incentive. Someone may (will) have to pick up on what I come up with.
