When I fullscreen a normal movie player, such as totem, and go to the overview mode by hitting the window key, I see an approximation of the fullscreen display, which updates in the overview. Hitting the window key again returns me to the fullscreen window.

When I fullscreen a browser-based flash movie player (youtube, espn3, whatever), and go to the overview mode by hitting the window key, I see the non-fullscreen version of the window, which does not update. Hitting the window key again returns me to the fullscreen window.

Unsure whether the shell can be fixed to support this (it is flash, after all), but filing for reference in case it can be handled.
