filling a bug in bugzilla is too complicated for me then i report some issues in fedora 17 beta RC3 (64bit) GNOME here.
it is a thinkpad laptop with intel chips. system is updated.
1- clicking on "Activities" randomly restarts the gnome-shell (automatically).
2- "service NetworkManager restart" in terminal makes gnome-shell restart.
3- firefox doesn't show many videos in youtube or some flash movies on other web sites have not toolbar(flash 64 is installed).
4- firewall-applet for firewalld is not installed by default and after installing doesn't show any notification.
5- there is no firewall-config! i think it is GUI for firewalld...
6- alacarte doesn't work as always.
7- cpu governer ondemand is not a good default(at least for desktops) and why do you insist on it? up_threshold 95 doesn't work always and system becomes slow or hangs.
8- i don't know is it power-manager or my hardware but connecting laptop to power makes system too slow!(bios is updated and power supply is new)
