Good news: (1) I can finally reproduce the crash today.
(2) My original analysis failed to notice that the offending JavaScript code simply doesn't exist in Gnome Shell 3.30 and later. So that's why this bug only exists in 3.28 (Ubuntu 18.04). ** Bug watch added: gitlab.gnome.org/GNOME/gnome-shell/issues #927 https://gitlab.gnome.org/GNOME/gnome-shell/issues/927 ** Also affects: gnome-shell via https://gitlab.gnome.org/GNOME/gnome-shell/issues/927 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1812527 Title: [bionic][regression] gnome-shell crashes with SIGSEGV in meta_window_actor_is_destroyed(self=NULL) called from _switchWorkspaceDone() [windowManager.js:1787] Status in GNOME Shell: Unknown Status in gnome-shell package in Ubuntu: Invalid Status in gnome-shell source package in Bionic: In Progress Status in gnome-shell source package in Eoan: Invalid Bug description: https://errors.ubuntu.com/problem/cb400a6f83ed57af8bb117cf84d5ed6d7e2ffcee https://gitlab.gnome.org/GNOME/gnome-shell/issues/927 Switching workspace with the Android Emulator running will blink the screen as if gnome restarted, if I switch workspace one more time, it will completely crash and I will need to log in again.
