PyQt5 Python Transparent QWebViewEngine

Question

I am trying to get the QWebEngineView to be transparent. I saw things online, but that would make the entire background transparent (IE the window, not the "image"). I am use Qt Designer and Python 3.

If you look at this

you will see that the .png is transparent, but is not showing the default black background (IE would actually be transparent). I have tried to auto-fill the background and use settings such as ".setAttribute(Qt.WA_TranslucentBackground, True)", but again this make the window transparent, not the web page results.

UI file:

Py file:

from PyQt5 import QtCore, QtGui, QtWidgets, uic
from PyQt5.QtWidgets import QMainWindow, QDialog, QTableWidget, QTableWidgetItem, QListWidget, QListWidgetItem, QLabel, QGraphicsPixmapItem, QDockWidget, QSplashScreen
from PyQt5.QtGui import QPixmap
from PyQt5.QtWebEngineWidgets import QWebEnginePage
from PyQt5.QtWebEngineWidgets import QWebEngineView
import os
import sys

class MainWindow(QMainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()
        uic.loadUi(str(os.getcwd()) + "\\" + 'ui.ui', self)
        self.show()

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)

    window = MainWindow()
    sys.exit(app.exec_())

To the person that commented. When I use the same image as you I get .
