Thanks. The only thing possibly related that I can see is this occurred on a couple of occasions:
Apr 08 09:52:37 jays-pc gnome-shell[9871]: JS ERROR: Extension dash-to-d...@micxgx.gmail.com: TypeError: appIconPrototype._onLeaveEvent is undefined _init@/home/jay/.local/share/gnome-shell/extensions/dash-to-d...@micxgx.gmail.com/appIcons.js:1052:9 So in the least it seems you're not using Ubuntu packages for your dock, which makes this bug Invalid. Please uninstall all your extensions (or just delete ~/.local/share/gnome-shell/extensions/) and report a new bug for any further problems you might find. ** Changed in: gnome-shell-extension-ubuntu-dock (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell-extension-ubuntu-dock in Ubuntu. https://bugs.launchpad.net/bugs/1871534 Title: Ubuntu dock causes Gnome shell to crash Status in gnome-shell-extension-ubuntu-dock package in Ubuntu: Invalid Bug description: Ubuntu dock is causing the gnome shell to crash especially while opening appfolders and clicking out of the app folders. Same problem was also observed during minimizing and maximizing (by clicking the launcher button). The entire gnome shell was frozen; none of the key bindings worked - except the only option was to switch to the tty by hitting alt-ctrl-f3 and restart from there. I have played around with all the options in the settings by installing dash to dock extension (since some settings seems to be shared) including transparency, Auto hide, panel & icon size with all kinds of combinations and I managed to fix this issue by disabling / unchecking the option: Panel mode:extend to screen edge. After disabling/Unchecking the option- Panel mode:extend to screen edge; this problem could not be replicated again. lsb_release -a No LSB modules are available.
