Different icons for checkable QPushButton is not works on Linux and Android

Hello. I want to make different icons for checked and unchecked state of QPushButton. The code:

Code:

---

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
{
    QBoxLayout *layout1 = new QVBoxLayout();
 
    QWidget *widget = new QWidget(this);
    widget->setLayout(layout1);
    setCentralWidget(widget);
 
    QIcon icon1;
    icon1.addFile(QStringLiteral(":/norecord.png"), QSize(), QIcon::Normal, QIcon::Off);
    icon1.addFile(QStringLiteral(":/active.png"), QSize(), QIcon::Normal, QIcon::On);
 
    QPushButton *button1 = new QPushButton(this);
    button1->setCheckable(true);
    button1->setText("Sample Text");
    button1->setIcon(icon1);
    layout1->addWidget(button1);
 
}

I use Qt 5.15.2. This code works in Windows, but not in Linux and Android, there always shows an icon for a unchecked state.
On Qt 5.11.3 and earlier versions it worked.

As far as I could understand, the problem causes this code in the Fusion style, file src/widgets/styles/qfusionstyle.cpp:

Code:

---

case CE_PushButtonLabel:
        if (const QStyleOptionButton *button = qstyleoption_cast<const QStyleOptionButton *>(option)) {
            QStyleOptionButton b(*button);
            // no PM_ButtonShiftHorizontal and PM_ButtonShiftVertical for fusion style
            b.state &= ~(State_On | State_Sunken);
            QCommonStyle::drawControl(element, &b, painter, widget);
        }
        break;

I want to ask: Is it a correct code? Is it a bug or style feature?

I would guess you're using the fusion style?

Yes, Fusion. Thanks. Fixed at 6.1...
