After minimizing and restoring a window, or switching virtual desktops, xcompmgr stops responding to _NET_WM_WINDOW_OPACITY changes, and needs to be restarted. The reason is that XSelectInput is called in add_win to listen for the changes, and then in unmap_win to stop listening, but never in map_win. I'll attach a patch that fixes it.
