Comment 18 for bug 967294

The new behaviour tells "this menu now, isnt of the maximized window. but of something else".

IMO, even if it is necessary to convey this message, it should be done by a (black?) line [border] of 3-5px width. Definitely not a shadow 15 px long with gradient which is about 10px more obtrusive for the underlying maximized app.

In my use, I often keep one window maximized and one not-maximized for a reason: to be able to see the maximized content not overlapped by the unmaximized window. If at all overlap exists in a portion I want to see, I can move the un maximized window.
The 15 px height shadow cannot be moved, and will obstruct no matter what.
Whether or not those 15 px on top will hold any information which is important is a different issue, but the obstruction should be minimum, and flat. Gradients for borders are painful to look at, and gives me a feeling the composting manager has caused the issue, rather than an intended behaviour.
