我正在建立一个qml应用程序，我想实现一个圆圈，里面有一个“波”的效果。我或多或少成功了，除了结果是这个图形伪像...有人能帮助我吗？
问题在于：

工作示例不带圆：

我声明我从来没有使用过qml在我的生活，这是第三天我一直在它的工作，当然我试图阅读文档等，但我不知道发生了什么，这是代码：

//QT PK
import QtQuick 2.2
import QtQuick.Window 2.0
import QtQuick.Controls 1.1
import QtQuick.Controls.Styles 1.1
import QtGraphicalEffects 1.0
//JS PK
import "componentCreation.js" as MyScript

ApplicationWindow 
{
    id: window
    flags: Qt.FramelessWindowHint
    visible: true
    title: qsTr("window")
    width: 1600
    height: 900
    x: (Screen.width - width) / 2
    y: (Screen.height - height) / 2
    color: "transparent"

    property real slideValue
    signal onSlide(real value)

    Image 
    {
        id: img
        source: '/home/patan/code/QML/pic/contents/images/Waves.png'
        property bool rounded: true
        property bool adapt: true

        //MAKE IMAGE CIRCULAR
        layer.enabled: rounded
        layer.effect: OpacityMask 
        {
            maskSource: Item 
            {
                width: img.width
                height: img.height
            
                Rectangle 
                {
                    anchors.centerIn: parent
                    width: img.adapt ? img.width : Math.min(img.width, img.height)
                    height: img.adapt ? img.height : width
                    radius: Math.min(width, height)
                }
            }
        }
        //WAVE EFFECT
        ShaderEffect 
        {
            anchors.fill: parent
            property variant source: img

            }
            fragmentShader: "
                            varying highp vec2 qt_TexCoord0;
                            uniform sampler2D source;
                            uniform lowp float qt_Opacity;
                            uniform highp float frequency;
                            uniform highp float amplitude;
                            uniform highp float time;
                            void main() {
                                highp vec2 texCoord = qt_TexCoord0;
                                texCoord.y = amplitude * sin(time * frequency + texCoord.x * 6.283185) + texCoord.y;
                                gl_FragColor = texture2D(source, texCoord) * qt_Opacity;
                            }"
        }
    }
}

请原谅我，如果这是可怕的代码质量，如果任何人可以帮助我得到它的工作，我将不胜感激
