I am also seeing this problem, which seemed to manifest itself after a recent update. By experimenting, I've determined that there seems to be a segfault in libmutter-2.so.0.0.0 each time the workspace changes (when the Android emulator is running).
Please see the attached excerpt from my syslog. I see this each time I try to switch to a different workspace, if the *current* workspace contains an open emulator window. The problem doesn't seem to happen if the emulator window is minimized. Please let me know if you need any more info. ** Attachment added: "Excerpt of lines in syslog that occur each time workspace is switched" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1812527/+attachment/5230924/+files/var-log-syslog-excerpt.txt -- 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: gnome-shell crashes when switching from workspace that is running Android emulator (QEMU) Status in gnome-shell package in Ubuntu: Incomplete Bug description: 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.
