I have a theory, and it isust a theory... The hotkey to change desktops is Ctrl+Alt+UP/DOWN The hotkey on the Android emulator to pinch zoom is Ctrl+Alt with mouse drag.
When the emulator is the active window, and you press Ctrl+Alt, then a graphic appears on the emulator showing the pinch zoom function. This graphic is often left on the display as an artefact overlayed on the new desktop, when the crash occurs. As I said, just a theory, and I don't want to point anyone in the wrong direction :) -- 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 gjs package in Ubuntu: Confirmed Status in gnome-shell package in Ubuntu: Confirmed Status in gjs source package in Bionic: Confirmed Status in gnome-shell source package in Bionic: Confirmed 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.
