I think it is a bug in Qt, reported as https://bugreports.qt.io/browse/QTBUG-67537.
Another possible workaround: export QT_XCB_GL_INTEGRATION=xcb_egl (the bug is in the xcb_glx integration plugin, this environment variable will switch to a different integration plugin). ** Package changed: pyqt5 (Ubuntu) => qtbase-opensource-src (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtbase-opensource-src in Ubuntu. https://bugs.launchpad.net/bugs/1761708 Title: QWebEngineView crashes Status in qtbase-opensource-src package in Ubuntu: Triaged Bug description: I have KUbuntu 18.04 with the latest updates.
