qwqwqw2

phone: redmi
android version: android 10
qt version: qt 6.7

my app screen orientation is landscape
the phone screen has safe area

top     : 0
left    : 28
bottom  : 0
right   : 0

c++ code:

QObject::connect(p->screen, &QScreen::availableGeometryChanged,
                     [&](const QRect &){
                         TIP_COUT << "availableGeometryChanged:" << p->screen->availableGeometry();
                     });

qml code:

ApplicationWindow {
    minimumWidth: 1560
    minimumHeight: 720
    visibility: Qt.platform.os === "windows" ? Window.Minimized
                                             : Window.FullScreen
  ........
}

app first start, output:

availableGeometryChanged: QRect(0,0 851x393)

when i turn to main screen or drag down the notification drawer
screen size will changed, output:

availableGeometryChanged: QRect(0,0 822x393)

the witdh parameter minus left safe area value

how fix?
