[Interest] QIcon addFile 10 seconds slower than addPixmap

[nus1998]

Hi All,


I'm developing an application on an embedded system which use linuxfb as the qpa plugin, and the qt is 5.9.6
In some UI pages that generated automatically by qmake, I found that icon.addFile(QStringLiteral(":/image/icons/ok.png"), QSize(), QIcon::Normal, QIcon::Off); cost 10 seconds, however, if I change it to icon.addPixmap(QStringLiteral(":/image/icons/ok.png"), QIcon::Normal, QIcon::Off); it will be executed immediatelly. as the addFile method is the default method that qmake works, I wonder what I can do to avoid this low waiting in addFile?
