I've attached a hopefully a good example of the behaviour, this time affecting Chrome.
In the foreground is Gnome Terminal, with transparency enabled (and a dmesg output just to have text appearing). Behind it you can see Google Chrome on the Google home page. In the alt+tab box you can see just Desktop and Terminal. To get Chrome to appear in the alt+tab box I had to switch to it (using dock icon) then press alt+tab whilst it had focus. Alt-tabbing between then works fine. ** Attachment added: "Hopefully a good example" https://bugs.launchpad.net/ubuntu/+source/unity/+bug/951929/+attachment/2852850/+files/example.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/951929 Title: alt+tab doesn't show gnome-terminal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/951929/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
