Hi, I met window missing just now, based on ppa version. But when I use Ctrl + Shift + I to debug, I found out that the debug window is also unable to display.
Luckily, I was using nemo, so I switch to tty1 and run: DISPLAY=:0 gsettings set org.nemo.desktop show-desktop-icons false Then switching back to desktop, all windows came back. So it is definitely the background cover all windows. If I execute "gsettings set org.gnome.gnome-flashback desktop-background true", then it will also cover all windows, which is similar to this issue but this issue is cause by nautilus/nemo covering other windows. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to metacity in Ubuntu. https://bugs.launchpad.net/bugs/1538111 Title: untraceable serious bug in metacity 3.18 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/metacity/+bug/1538111/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
