[Touch-packages] [Bug 1435465] Re: Alt+F4 crashes app where WebView embedded in a Window
The full story is that after the commit it was reverted in 5.6 https://codereview.qt-project.org/#/c/147886/ with a comment "It's too risky for 5.6, we should let it cook in dev for a while and backport when ready.", but then also that revert got merged to dev so as far as I can see upstream does not have any fix for the bug :( I asked in the bug report two days ago whether there's going to be some activity on it, and then in addition to dev it'd be nice to have some non-risky 5.6 variant of it. -- 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/1435465 Title: Alt+F4 crashes app where WebView embedded in a Window Status in qtbase-opensource-src package in Ubuntu: Confirmed Bug description: was just watching something on Youtube Web App created by unity itself. when i pressed alt-f4 Ubuntu said it had an error and if i want to submit it. that is all folks.

[Touch-packages] [Bug 1435465] Re: Alt+F4 crashes app where WebView embedded in a Window
The difference between having the root item of the scene being a plain Item or a Window is that I’m seeing the destructor for BrowserThreadQEventDispatcher being called (Item) or not (Window). When the root item of the scene is not a Window, qmlscene wraps the scene in a QQuickView, which inherits from QQuickWindow. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to webbrowser-app in Ubuntu. https://bugs.launchpad.net/bugs/1435465 Title: Alt+F4 crashes app where WebView embedded in a Window Status in Oxide: New Status in webbrowser-app package in Ubuntu: Confirmed Bug description: was just watching something on Youtube Web App created by unity itself. when i pressed alt-f4 Ubuntu said it had an error and if i want to submit it. that is all folks.

I can reliably reproduce the crash with the following minimal QML scene
(run in qmlscene):
import QtQuick 2.4
import QtQuick.Window 2.2
import com.canonical.Oxide 1.15
Window {
width: 400
height: 300
WebView {
anchors.fill: parent
url: "http://example.org";
}
}

[Touch-packages] [Bug 1435465] Re: Alt+F4 crashes app
Crash is still happening even with the latest changes to the shutdown sequence in oxide trunk. I’ve observed that closing a window by sending it a _NET_CLOSE_WINDOW message (using e.g. wmctrl -c) doesn’t trigger the crash, so it’s really only the Alt+F4 keyboard shortcut that causes the issue. ** This bug is no longer a duplicate of bug 1448079 Don't run the event loop after QGuiApplication begins to tear down -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to webbrowser-app in Ubuntu. https://bugs.launchpad.net/bugs/1435465 Title: Alt+F4 crashes app Status in webbrowser-app package in Ubuntu: Confirmed Bug description: was just watching something on Youtube Web App created by unity itself. when i pressed alt-f4 Ubuntu said it had an error and if i want to submit it. that is all folks.
