Rotating the mouse wheel when QML app is starting results in frozen UI

XMLWordPrintable

    • Windows

      1. Create an empty QtQuick app from Qt Creator.
      2. In main.qml set this code:
      import QtQuick 2.12
import QtQuick.Controls 2.5
import QtQuick.Window 2.12

Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")    
    Button {
        text: "TEST"        
        onClicked: {
            text = "PASSED"
        }
    }
}
      1. Compile the app.
      2. Start the app without debugging and immediately start rotating the mouse wheel (don't stop).
      3. Once the application is started, stop rotating the wheel and try clicking the Button.
      4. UI is frozen: you cannot click the Button.
