Hi,guys: I have a question about gnome-shell popup menu,I found actives bar will block app's popup menu when popup menu too long. is it my setting have some problem?? http://imagebin.org/197986 you can see actives bar block list

Ok, I didn't notice anything out-of-ordinary on your screenshot, seems like its ok since the focused application is on top layer and overlaps the bar. I don't think that is a bug. 你会放心点儿:)

ok,beacause actives bar is transparent , please notice list top position,if actives bar isn't transparent, you will not see the top of list
