Hi guys, i got an issue using QtWebEngine under linux => nothing appear into the QWebEngineView (working pretty well under Windows 10

Here my config:
Linux Ubuntu Mate 22.04
Linux kernel 5.15.0-46
Python 3.10
PySide2 5.15.2.1 (also try with 5.13.2/5.13.1/5.13.0)

Here the code:

import sys
import os
from pathlib import Path

from PySide2.QtWidgets import QApplication, QMainWindow

from PySide2.QtCore import QFile

from PySide2.QtUiTools import QUiLoader
from PySide2.QtWebEngineWidgets import *

class Trader(QMainWindow):
    def __init__(self, parent):
        super(Trader, self).__init__()
        self.parent = parent

        loader = QUiLoader()

        path = os.fspath(Path(__file__).resolve().parent / "form.ui")
        ui_file = QFile(path)

        ui_file.open(QFile.ReadOnly)
        self.ui = loader.load(ui_file, self)

        ui_file.close()

        self.web = QWebEngineView()
        print(self.web.load("https://www.google.fr"))

        self.ui.view_layout.addWidget(self.web)

        self.showMaximized()

if __name__ == "__main__":
    app = QApplication([])

    widget = Trader(app)

    sys.exit(app.exec_())

Hello and welcome.

Did you try loading a non-https URL? Or putting slots on any of its signals to see if anything is being reported?

i justed try:

http / https had same issue

with checking the signals i can figure out that

the signal renderProcessTerminated is emit right after initialisation of QWebEngineView object with:
status = PySide2.QtWebEngineWidgets.QWebEnginePage.RenderProcessTerminationStatus.CrashedTerminationStatus
exit code = 159
then i use QWebEngineView.load(url) method
-loadStarted is emit
-loadProgress(1) is emited
the signal renderProcessTerminated is emit right after initialisation of QWebEngineView object with:
status = PySide2.QtWebEngineWidgets.QWebEnginePage.RenderProcessTerminationStatus.CrashedTerminationStatus
exit code = 159
-loadProgress(100) is emited
