This may be related to https://bugs.launchpad.net/ubuntu/+source/metacity/+bug/1614050 , which is about wrong window depth ordering. The original bug described (all windows closed) already turned out as "all windows hidden" here. It seems the desktop (featuring a background image) may pop in front of all other windows.
The bug linked here describes an almost similiar situation, where the desktop icons appear in front of all windows, this has likely the same reason except the desktop background itself is transparent in this case. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
