Hi, I upgraded from Qt v5.14.0 to v5.15.2. When opening my v5.14.0 projects with the new version; I noticed that the font in all my ui files reset to default 'Segoe'. Comparing the ui header files from my v5.14.0 build and v5.15.2 builds I noticed that the lines font.setFamily(QString::fromUtf8("Arial")); had simply disappeared along with font.setWeight(75); . This has occured on multiple projects that I have built with the newer version where the font family gets reset. What is going on ? v5.14.0 sample ui.h: QFont font; font.setFamily(QString::fromUtf8("Arial")); font.setPointSize(36); font.setBold(true); font.setWeight(75); label_2->setFont(font); v5.15.2 of the same file: QFont font; font.setPointSize(36); font.setBold(true); label_2->setFont(font);

Fixed In Qt6.2.3 and Qt6.3 so I would guess when a new QtCreator is build with Qt6.2.3 it's fixed there too. See https://bugreports.qt.io/browse/QTBUG-98916

<font family> gets removed from .ui header files after upgrading Qt Creator from v5 to v6 ?

Does the same problem exist if you use Qt 6.x Designer directly rather than as a component included in QtCreator?
