Animated FastBlur causes Qt Quick application to crash on exit

brachna

Hello.

I have a problem with animated ShaderEffect, FastBlur. When application exits after playing animation it crashes with following statement: "Error - RtlWerpReportException failed with status code :-1073741823. Will try to launch the process directly".
If I change ending radius value to 0. it will not crash on exit.
Not sure if it's a bug or I made some mistakes that lead up to that.

Application is the default Qt Quick 2.2 application (no changes) with following QML file:

@import QtQuick 2.2
import QtQuick.Window 2.1
import QtGraphicalEffects 1.0

Window {
visible: true
width: 360
height: 360

MouseArea {
    anchors.fill: parent
    onClicked: {
        if ( mouse.button == Qt.LeftButton ){
            animations.restart();
        }
    }
}

SequentialAnimation {
    id: animations;
    NumberAnimation {
        target: coverBlur;
        property: "radius";
        from: 0.0;
        to: 64.0
        duration: 2000;
        easing.type: Easing.InOutQuad
    }
    NumberAnimation {
        duration: 3000;
    }
    NumberAnimation {
        target: coverBlur;
        property: "radius";
        from: 64.0;
        to: 0.0
        duration: 2000;
        easing.type: Easing.InOutQuad
    }
}

Rectangle {
    id: albumRect;
    width: parent.width;
    height: parent.height;
    color: "transparent";

    FastBlur{
        id: coverBlur;
        source: coverImg;
        anchors.fill: coverImg;
        radius: 64;
    }

    Image {
        id: coverImg;
        smooth: true;
        anchors.rightMargin: 10;
        anchors.leftMargin: 10;
        anchors.bottomMargin: 10;
        anchors.topMargin: 10;
        anchors.fill: parent;
        source: "qrc:///cover.png";
        opacity: 1.0;
        fillMode: Image.PreserveAspectFit;
        visible: false;
    }
}

So it was a bug after all. Thanks for reporting. Hope it will be resolved in Qt 5.3.
