This bug has shown itself several times with xchat-gnome. When I start xchat-gnome either from the indicator-session menu or from the Unity dock, it is completely invisible but 'ps ax' shows an xchat-gnome process.
Large part of the screen is unclickable. Killing xchat-gnome and restarting it solves the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/709461 Title: semi-random invisible window with x geometry on top layer possible, all viewport only (one ws though) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
