Description
When trying to run this simple PyQt application:
import sys from PyQt5.QtCore import QUrl from PyQt5.QtWidgets import QApplication from PyQt5.QtWebEngineWidgets import QWebEngineView app = QApplication(sys.argv) wv = QWebEngineView() wv.load(QUrl('https://www.qutebrowser.org/')) wv.show() app.exec_()
I get:

This seems similar to QTBUG-66668, but happens on the current 5.11.0 branch on Linux (i.e. with that fix in, and not on Windows).
I can't reproduce it with a C++ example for some reason, but I don't see how this could be a PyQt issue either...
It does not happen with whatever MaintainanceTool calls 5.11.0-201804081744 (I think that was beta 3?), but does happen with 5.11.0-201804181845 (beta 4) and the current 5.11.0 head.
It also does not happen in my more complex PyQt application for some reason...
