gnome-shell hang (overview / drag-drop)
Was in overview screen, re-arranging windows across monitors after plugging in 2nd monitor, when gnome-shell locked up hard. Had to reboot machine.
This was on fedora 29 install.. I think v3.30.2 (but I did a dnf-upgrade after rebooting..)
Attached journalctl --boot=-1: gs-hang.log
Looks like a lot of msgs were dropped so it didn't capture the very first error msgs.
