I have GNOME Shell 220.127.116.11 with compiz enabled. Everything works great for the most part, but I do have an issue whether I have compiz enabled or not. I am using fallback classic and whenever a window is maximized, and I want to unmaximize, minimize, or close a window, that window becomes unresponsive. BTW (UBUNTU 13.04) The two workarounds that I have found is using the application switcher which then I can use alt+f4 to close the window or using cairo-dock (no open-gl) after I use the app switcher to unmaximize. I tried upgrading to a newer gnome before but that was much worse. I would like to stay with this gnome as it is fairly stable on my machine. Any ideas? Thanks in advance.
