Comment 71 for bug 687567

I tried the updated unity from daniels ppa, but since i run a gnome classic session, i wasn't sure if/how the fix would affect me. And sure enough, this fix only covers unity, which of course begs the question - isn't that a clear indication that the problem lies deeper than that, perhaps in gtk/metacity/compis/dbusmenu itself? The *menubar* flickers when new windows are opened, in fact, if you remove the "indicator applet appmenu" from the gnome-panel, you can still see the flicker and menu repainting itself in the application window (of say nautilus, that never used to flicker like that) when new windows are spawned. Also, the drop downs from the menubar (when scrubbing it) causes flicker (both with indicator applet appmenu, and in-window menu).
Thoughts?
