Description
on Linux, for most styles (for instance Material is affected) the following code, doesn't show an icon anymore (worked fine in Qt 5.10 and 5.11):
Button
{ icon.name: "go-up" }
looking into QQuickIconImage::setName(), it loads the icon with
d->icon = QIconLoader::instance()->loadIcon(name);
if i do:
qDebug()<<QIconLoader::instance()->themeName(); i can see it has an empty theme name, instead of the system one.
If i add before loadIcon() the code:
QIconLoader::instance()->updateSystemTheme();
it sets the correct theme and the icon is loaded correctly.
updateSystemTheme doesn't seem to be called anywhere in either qtbase or qtquickcontrols2 repositories, where should this be done?
