Fullscreen window that is not focused shows behind the menu of a focused maximized window

[Ciro Santilli 六四事件 法轮功]

Ubuntu 16.04, just upgraded from 15.10.

To reproduce:

- open gnome-terminal or any window that can become fullscreen and make it fullscreen (F11)
- open any other window maximized and give it focus

Outcome: the background fullscreen shows behind the menu, making it hard to read.

See the top of the attached screenshot.

Do others reproduce on a fresh 16.04, or is it some package / setting that broke from 15.10?

Which theme are you using? Do you always have transparent panel?

@Andrea : the problem happens on Adwaita and High Contrast, but not Ambiance (default) and Radiance, which are not transparent.

I didn't know menu transparency was a theme setting, good catch. I forgot if those themes ship by default or if they're something I've installed.

Maybe it would be better if the theme engine didn't allow transparent menus like that, it always breaks UI.

Ok thanks. A fix has already been proposed and should be available in the next sru.
