Unsolved QComboBox Custom Paint Event Flickering Issue

[Emrecp]

Hello,
I am trying to create custom combobox.
Code:

    FontSize, FontSpacing = 16, 0
    Color = {
        "CORNER": QColor(214, 214, 216),
        "BASE_BACKGROUND": QColor(247, 247, 250),
        "BASE_FOREGROUND": QColor(255, 152, 91),

        "BASE_HOVER_BACKGROUND" :QColor(255, 152, 91),
        "BASE_HOVER_FOREGROUND": QColor(247, 247, 250),

    }
    TextElide = Qt.ElideMiddle

        pt.setRenderHints(QPainter.Antialiasing | QPainter.TextAntialiasing )
        border = QPainterPath()
        border.addRoundedRect(QRectF(self.rect().adjusted(2, 2, -3, -3)),self.ComboBoxData.Radius, self.ComboBoxData.Radius)


        pt.setPen(QPen(self.ComboBoxData.Color['CORNER'], 3.5))
        pt.setBrush(self.ComboBoxData.Color['BASE_BACKGROUND'])

        pt.drawPath(border)

        pt.setClipPath(border)




        pen = QPen(QColor(QtCore.Qt.black))
        #pen.setWidth(10)

        pt.setBrush(brush)



        w, h = self.width(), self.height()
        arrow_width, arrow_height = 12, 20
        arrow_margin_width, arrow_margin_height = 16, 14
        arrowBodyPoints= QPoint()
        pt.setPen(QPen(self.ComboBoxData.Color['CORNER'], 3));

        pt.setBrush(Qt.NoBrush)
        path2 = QPainterPath()
        path2.addPolygon(QPolygonF(
            [QPoint(w-arrow_margin_width-arrow_width, arrow_margin_height),QPoint(w-arrow_margin_width- (arrow_width/2),arrow_height),
             QPoint(w - arrow_margin_width - (arrow_width / 2),arrow_height), QPoint(w-arrow_margin_width,arrow_margin_height)

        pt.drawText(TextRect, Qt.AlignCenter, Text)




if __name__ == "__main__":
    app = QApplication(sys.argv)
    wind = QMainWindow()
    wind.setStyleSheet("QMainWindow{background-color:blue}")
    wind.setWindowTitle("EComboBox")
    wind.resize(221, 150)
    wid = QWidget()
    lay = QHBoxLayout(wid)
    lay.setAlignment(Qt.AlignCenter)
    
    Data = EComboBoxData()
    e = EComboBox(Data)
    e.addItems([ "Uzun bir yazı 123","Otomatik", "1 MB/sn", "5 MB/sn", "8 MB/sn"])
   
   
    lay.addWidget(e)
    wind.setCentralWidget(wid)
    wind.show()
    sys.exit(app.exec())

When click combobox for see items; It flickers.
