untraceable serious bug in metacity 3.18
Status in metacity package in Ubuntu:
Ubuntu 16.04 LTS uses 3.18 version of gnome metacity.
When doing lots of mess work in Desktop (such as open desktop window,
sudo window, dragging window, and so on), "!! WHEN CLICKING CLOSE
BUTTON OF A CERTAIN WINDOW !!", there is "small possibility" for
metacity to get out of work --> Many windows are disappeared, with
only nautilus desktop background and gnome-panel on screen. "Live
Window List" still exists in gnome-panel, but no matter doing what
(such as open new application from gnome-menu or use Alt+Tab to switch
window), none of live windows can be displayed.
So the only way is to switch to tty1 using Ctrl+Alt+F1, and executing
"DISPLAY=:0 metacity -c --replace", then all windows came back.
Till now, I meet this bug every day, but still not sure how to
reproduce it bug. I think you should trace what the metacity do when
clicking "close button" that makes all windows to be disappeared.
