I have seen the same problem clicking on links in thunderbird and Gwibber with firefox as the default browser.
However, I have *also* seen the problem when clicking on links in firefox opening PDF docs (as per screenshot). You can see evince in the front, but with Firefox tabs visible between the PDF doc and the Unity panel. It seems to appear if the link triggers a new app to be in front of the app with the link, but Unity doesn't change to the new app. ** Attachment added: "Screenshot1.png" https://bugs.launchpad.net/ubuntu/+source/unity/+bug/772044/+attachment/2098016/+files/Screenshot1.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/772044 Title: Weird maximized firefox glitch -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
