python - PyQt WebEngineView interferes with MainMenu -


i'm trying create application contains web browser within it, when add web browser menu bar visually disappears functionally remains in place. following 2 images, 1 showing "self.centralwidget(self.web_widget)" commented out, , other allows line run. if run example code, see while visually entire web page appears if menu bar wasn't present, have click below each entry field , button in order activate it, behaving if menu bar in fact present.

web widget commented out enter image description here

web widget active enter image description here

example code

import os import sys pyqt5.qtwidgets import * pyqt5.qtcore import * pyqt5.qtwebenginewidgets import *  class webpage(qwebengineview):     def __init__(self, parent=none):         qwebengineview.__init__(self)         self.current_url = ''         self.load(qurl("https://facebook.com"))         self.loadfinished.connect(self._on_load_finished)      def _on_load_finished(self):         print("url loaded")  class mainwindow(qmainwindow):     def __init__(self, parent=none):         # initialize main window         super(mainwindow, self).__init__(parent)         self.create_menu()         self.add_web_widet()         self.show()      def create_menu(self):         ''' creates main menu '''         self.main_menu = self.menubar()         self.main_menu_actions = {}          self.file_menu = self.main_menu.addmenu("example file menu")         self.file_menu.addaction(qaction("testing testing", self))      def add_web_widet(self):         self.web_widget = webpage(self)         self.setcentralwidget(self.web_widget)  if __name__ == "__main__":     app = qapplication(sys.argv)     main_window = mainwindow()     main_window.showmaximized()     sys.exit(app.exec_())  # need 1 app, 1 running event loop

development environment windows 10, pyqt5, pyqt5-5.9

edit

the problem doesn't seem directly related menu bar. removing menu bar issue still occurs. said, changing showmaximized() showfullscreen() seem solve problem.

i no longer believe issue pyqt5 rather problem graphics driver. specifically, if @ atlassian's hipchat application has similar problem documented here: https://jira.atlassian.com/browse/hcpub-3177

some individuals able solve problem running application command prompt addendum "--disable-gpu" didn't work python application. on other hand, rolling intel(r) hd graphics driver did solve problem. version 21.20.16.4627 1 seems causing problems.
