I can reproduce this bug though I too had some trouble at first understanding what this is about. This is using Metacity.
* Add the workspace switcher to your GNOME panel. * Start gedit and bring it to the front, you'll notice the gedit icon is being shown in the workplace switcher * Start alltray and dock gedit * Show gedit using alltray and make sure it's on top * The gedit icon will shortly appear in the workplace switcher, but then disappear Same for the workspace switcher that is brought up using CTRL + ALT + Left arrow / Right Arrow, it shows the icon from the program below the one that is docked (but shown). ** Changed in: alltray (Ubuntu) Status: Invalid => New -- alltray hides applications from gnome-panel desktop switcher https://bugs.launchpad.net/bugs/118484 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
