Hi, I am happy to report that there is no window missing at the moment, and compared with the original version, I found out a different phenomenon after applying this test.patch.
As has been said above, previously when I was using metacity original version, there is a small possiblity of window missing. But now, there is no window missing, instead, there is a small possiblity for the whole desktop to be turned dark slightly and then recover in very short time, approximately 0.1 to 0.5 second. The focus state of windows are correct so this new issue isn't a big deal. And this issue only happenes after adding this patch. I think this new version would be better than the orignial version, because users can at least work normally without replacing window manager when missing windows. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to metacity in Ubuntu. https://bugs.launchpad.net/bugs/1538111 Title: untraceable serious bug in metacity 3.18 Status in metacity package in Ubuntu: Confirmed Bug description: 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. Thanks.
