Description of problem: Gnome-shell hangs on Alt+Tab menu,this occurs frequently but not all the time. The Alt+Tab menu is still active and I can switch between open applications, but the menu itself won't disappear and crashes the gnome-shell (other applications cannot be started). Cannot restart gnome-shell through Alt+F2, as I'm not able to type 'r' on the run-command (keyboard won't work). I don't have any alt+tab gnome-shell extensions installed. I have AMD ATI Radeon 4xxx HD with Opensource Drivers. I switch to run-level 3 and get back to run-level 5 to restart gnome-shell. Version-Release number of selected component (if applicable): 3.6.3 How reproducible: Frequently Steps to Reproduce: 1. Press Alt + Tab 2. 3. Actual results: Alt+Tab menu won't disappear, preventing any applications to be launched or be interacted with (no keyboard interaction). Can view open applications, but the alt+tab menu won't disappear after choosing an application. Expected results: Alt+Tab menu should disappear after I choose an application and I should be able to launch new processes and interact with my applications. Additional info:

This message is a reminder that Fedora 18 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 18. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '18'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 18's end of life. Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 18 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 18's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug.
