This is really getting a big problem since I cannot use the emulator for my daily work. Is there anything I can do to help debug this? It is quite easy to reproduce as it happens every time I switch workspace with the emulator running, no matter what state the emulator is in; meaning the developers of this can easily reproduce this themselves: 1) Install full Android Studio with JDK, e.g. in ~/opt/android-studio to not pollute their computer 2) Start the Emulator; install any Android version in the process. 3) Switch Workspace. 4) Observe crash. -- 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/1812780 Title: Gnome Shell crashes with SIGSEGV when Android emulator started Status in gjs package in Ubuntu: Incomplete Status in gnome-shell package in Ubuntu: Incomplete Bug description: I am filing this bug with gjs because the behaviour started after upgrading to 1.52.5-0ubuntu18.04.1 Steps to reproduce are: 1.
