I just tried alpha-background and noticed a couple of seeming inconsistencies: the text area displays the set amount of opacity regardless of whether the frame is in focus or not, but while the tool bar remains completely opaque in both case, the menu bar is completely opaque when the frame is not in focus but completely transparent (regardless of the setting of alpha-background) when the frame is in focus (see attached images). Are these differences expected?
