Bug 1062269

I am having the exact same crash several times a day.

The worst case happens when I unlock the session, as it leads to a complete session loss.

A way I found to reproduce the crash quite easily:

- launch a VirtualBox VM
- plug in an external monitor
- plug it out

gnome-shell should crash to login window.

I could reproduce it :

    new empty user, same machine (thinkpad)
    another machine (macbook)
    cannot reproduce in cinnamon (so probably not gtk3 stuff)

I could reproduce it on the second machine only after a zypper dup on Tumbleweed.

So a new update definitely broke something, and it is probably not impacting only me.

In case the bug does not trigger immediately, just plug/unplug the external monitor several times.

Also, it does not matter whether it is a X11 or a Wayland session.

I don't know if this belongs in the same bug or not, but I see the same complaints in the journal after gnome-shell crashes and reloads when closing the mail evolution window from the gnome-shell Activities overview. It does not happen when the same window is closed without going to the overview mode, for example by directly clicking the [x] close-window button on the titlebar, or on Ctrl-Q. It also happens when closing firefox, gnome-documents and a few other apps from the g-s Activities overview.

possibly related to https://bugzilla.gnome.org/show_bug.cgi?id=788666 (which we just fixed in mutter in GNOME:Factory - fix submitted to openSUSE:Factory)

@Dominique,

I grabbed the mutter package from there:

http://download.opensuse.org/repositories/GNOME:/Factory/openSUSE_Factory/x86_64/

% rpm -qa mutter
mutter-3.26.1-270.4.x86_64

Unfortunately, the issue is still present.

Should I update other dependencies as well or does it demonstrate that the issue differs?

Same with mutter-3.26.1-271.1

I got a crash while closing a maximized window (Chrome), so either the upstream patch is not sufficient, or the patch is not applied in Gnome:Factory.

I have the same issue. It happen time to time, but also when qemu launches virtual machine.

I think bug #1062904 is related to this one.

Indeed, mutter-3.26.1-271.2.x86_64 from Gnome Factory seems to fix the issue.

It has not crashed so far.

Actually, the issue is less frequent but still occurs:

```
oct. 21 13:26:00 susepad gnome-shell[3029]: The program 'gnome-shell' received an X Window System error.
                                            This probably reflects a bug in the program.
                                            The error was 'BadWindow (invalid Window parameter)'.
                                              (Details: serial 131250 error_code 3 request_code 18 (core protocol) minor_code 0)
                                              (Note to programmers: normally, X errors are reported asynchronously;
                                               that is, you will receive the error a while after causing it.
                                               To debug your program, run it with the GDK_SYNCHRONIZE environment
                                               variable to change this behavior. You can then get a meaningful
                                               backtrace from your debugger if you break on the gdk_x_error() function.)
oct. 21 13:26:00 susepad systemd-coredump[6876]: Process 3029 (gnome-shell) of user 1000 dumped core.
```

No core dump:

```
% coredumpctl gdb 3029

```

Version (Mutter from Gnome factory, gnome-shell from Tumbleweed):

```
% rpm -qa gnome-shell
gnome-shell-3.26.1-1.1.x86_64
% rpm -qa mutter     
mutter-3.26.1-271.2.x86_64
```

I think it is fixed here for mutter as well as for other apps:
https://bugzilla.gnome.org/show_bug.cgi?id=788666#c27

Over the last 2 days, I tested latest versions from Gnome:Factory:

% rpm -qa gnome-shell
gnome-shell-3.26.1-360.1.x86_64
% rpm -qa mutter     
mutter-3.26.1-274.1.x86_64

And all issues vanished, so I think it has been fixed indeed.

Let's hope it can make it quickly to Tumbleweed...

same for me, with latest packages from Gnome factory it is not reproducible.

Marking as fixed in accordance with previous comments (fix has been incorporated into TW)
