Description of problem: GNOME Shell is prone to crash when switching focus and using input methods. See https://gitlab.gnome.org/GNOME/mutter/issues/353 . Backport the crash fix.
Could you provide some specific steps to reproduce the crash? The description is rather sparse.
I haven't reproduced it myself, but the reporter upstream have tested the patch. A description of how to reproduce, as written by the upstream reporter is: > By the way, crash occurred with high probability when moving focus from gnome-terminal to firefox, while executing app in terminal which frequently update last line to display some sort of progress message.
Fix from upstream is backported to the f29 branch. Could be good to include in F29 thus requesting freeze exception. The impact of the bug is crashing the Wayland session when using input methods, though it is a race condition, and I don't know how often it is triggered, other than the reported reproduced it a couple of times a day.
mutter-3.30.1-5.fc29 has been submitted as an update to Fedora 29. https://bodhi.fedoraproject.org/updates/FEDORA-2018-0d6f9e6a07
+1 FE
Yeah, I have heard about some unexpected Wayland behaviour from a colleague, this can be connected to this. Therefore +1 FE.
+1 FE, makes sense to get simple crash fixes in as the compositor crashes are super user visible (they bring down the whole Wayland session with them).

I might have this crash and be very easily able to trigger it. It happens to me about once every 30 minutes :( Gnome shell crashes for me with SIGABRT and I get tossed to the login manager. I upgrade to mutter-3.30.1-5 but still experience the issue. Unfortunately the backtrace is 1.3GB and it won't upload from the crash screen. Is there any way I can help diagnose this?
Kevin, does the backtrace match the one in the upstream issue? Does installing this: https://koji.fedoraproject.org/koji/buildinfo?buildID=1155400 build fix the issue?
Jonas, no, it doesn't match upstream, so probably a different issue. I installed the 3.30.1-5 from that source but it didn't change the issue. To reproduce the crash I'm having I can close Eclipse 2018-09, that will always trigger it. Judging from the unsymbolicated backtrace I have it could be this issue: https://gitlab.gnome.org/GNOME/mutter/issues/308 Should I raise an issue here in Bugzilla?
> Should I raise an issue here in Bugzilla? I don't see why not. Remember to link to the upstream issue, assuming its the same. If you can, also provide a backtrace with debug symbols (sudo dnf debuginfo-install mutter, then coredumpctl -r gdb gnome-shell, then bt full) to the upstream bug it'd be great.
