[Regression] Fullscreen window [close|min|max] buttons not clickable

[Achim]

I updates unity with proposed updates. I can't close a maximised window because the
window buttons disapper and so I can't click them.

Status changed to 'Confirmed' because the bug affects multiple users.

This happens to me for full screened windows. If I hover over the top bar the window buttons are shown, but once I move the cursor over the Unity bar they vanish so I can't click them. To close a window I have to first un-maximize it.

I think I noticed this bug while steam client was open. So I have no way to reproduce this reliably.

I have the same issue. I'm using Gnome classic desktop. When the window is maximized and focused I cannot click the metacity buttons. It will actually effect the window behind it. This has been happening since I upgraded to the newest release.
