As the original reporter does not respond, I tried to verify this myself (with Kubuntu 18.10 in VirtualBox).
Quite strangely, the attached test.qml file works fine even without the packages from -proposed. I was running it as “qml -qt5 test.qml” and it shows the StackExchange website properly. Then I tried to reproduce this with qutebrowser. By default qutebrowser disallows using Qt WebEngine backend with Wayland and shows a warning page when one tries to do that. However, it is possible to disable that by exporting QUTE_SKIP_WAYLAND_CHECK=1 environment variable: https://github.com/qutebrowser/qutebrowser/blob/v1.5.1/qutebrowser/misc/backendproblem.py#L223 When I run qutebrowser (with that variable set) with Qt WebEngine from cosmic-release, it behaves as described in this bug report (prints tons of warnings and does not load anything). After updating libqt5webengine* packages to cosmic-proposed versions, that is fixed. I think that is enough to mark this bug as verified. ** Tags removed: verification-needed verification-needed-cosmic ** Tags added: verification-done verification-done-cosmic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1803103 Title: QtWebengine doesn't work under wayland To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtwebengine-opensource-src/+bug/1803103/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
