Description
Doing alt-tab on Windows shows a thumbnail of the application's window.
It appears in the Windows taskbar as well.
But if the application is made visible directly with QWindow::showMinimized(), then no thumbnail is rendered.
Qt stops rendering when the window is minimized, which makes sense, but it would be useful to render at least the 1st frame, just so the thumbnail becomes more readable than an empty placeholder rectangle.
Example repro, run with: qml main.qml
import QtQuick 2.9
import QtQuick.Controls 2.15
ApplicationWindow {
visible: true
width: 500
height: 500
Rectangle {
id: root
color: "blue"
property int counter: 0
anchors.fill: parent
Text {
color: "white"
text: root.counter
font.pixelSize: 80
anchors.centerIn: parent
}
Timer {
interval: 1000
running: true
repeat: true
onTriggered: {
root.counter++;
}
}
}
Component.onCompleted: {
showMinimized();
}
}
