Android 5 fail to convet QQuickItem to QImage

[Zondar]

Hi,

I want to convert QQuickItem(Videooutput) to QImage, it works on Android 4.4, but when I tried it on Android 5(Samsung Galaxy s6), Videooutput works, but when I want to screen it prints "W/GLConsumer( 7947): [unnamed-7947-0] bindTextureImage: clearing GL error: 0x502"

VideoOutput {
id: videoOutput

    width: 400
    height: 400
    source: camera
    focus: true
    autoOrientation: true

    MouseArea {
        anchors.fill: parent
        onClicked: {
            imageHandler.makeScreenSync(videoOutput)
        }
    }
}

ImageHandler {
    id: imageHandler
}

//--------------------------------------------------------------------------------

QImage ImageHandler::makeScreenSync(QQuickItem *videoOutput)
{
QImage iresult = videoOutput->window()->grabWindow();
return iresult;
}
