GNOME Bugzilla – Bug 777183
Alt-tab crashes gnome-shell
Last modified: 2017-08-16 13:14:12 UTC
Intermittently, gnome-shell will crash with SIGSEGV when switching apps with alt-tab. See stack trace below. Generally when this occurs, I'm running Firefox and Chromium, each with several windows open, and gnome-terminal. I'm not certain, but it seems to only happen when I mouse over the app switcher. I'm running gnome-shell 3.22.2+18+gdf7727a-1 on Arch. Please let me know what other information I can gather! I'll update the bug if I can come up with a reproducible way to trigger the crash.

Yeah: https://bugs.freedesktop.org/show_bug.cgi?id=99396
Ah, thanks! Closing as NOTGNOME here as the problem seems to be lower in the stack.
