How to embed a pptk viewer in a PyQt5 window

Question

I am building a GUI program with PyQt5 (Qt Designer) which also uses the pptk library. This library can plot huge amount of points which is very interesting for my purpose (

Below is a demo script that shows how to add the viewer to a layout. I cannot test it on Windows, but on Linux (without the win32gui part), I get the results show below. As you can see, there is no weird border, and the window can be freely resized as normal.

from PyQt5 import QtWidgets, QtGui
import numpy as np
import pptk
import win32gui
import sys

class MainWindow(QtWidgets.QMainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()

        widget = QtWidgets.QWidget()
        layout = QtWidgets.QGridLayout(widget)
        self.setCentralWidget(widget)

        self.cloudpoint = np.random.rand(100, 3)
        self.v = pptk.viewer(self.cloudpoint)
        hwnd = win32gui.FindWindowEx(0, 0, None, "viewer")
        self.window = QtGui.QWindow.fromWinId(hwnd)    
        self.windowcontainer = self.createWindowContainer(self.window, widget)

        layout.addWidget(self.windowcontainer, 0, 0)

if __name__ == '__main__':

    app = QtWidgets.QApplication(sys.argv)
    app.setStyle("fusion")
    form = MainWindow()
    form.setWindowTitle('PPTK Embed')
    form.setGeometry(100, 100, 600, 500)
    form.show()
    sys.exit(app.exec_())
