Window management - when two windows of the same application are open, only one should have focus

[John Lea]

 When two windows of the same application are open, only one should have focus.

To reproduce:
1. Open two windows of the same application, e.g open two Chromium windows, or in Thunderbird click the "Write" button so that both the main window and the new message window are visible.
2. Arrange the windows so that they are both in the restored state (not maximised) and both their title bars are fully visible.
3. Notice that the title bars of both windows appear to be in focus simultaneously!

Desired correct solution:
- Only one widow should ever be in focus at one time, even if there are other windows of the same application open.
- See attached image "four_windows_in_focus_simultaneously.png" to see a state that should never be possible.
- The window decorations and window title in the window title bar should be grayed out for non-focused windows.

I have this problem and I am using an ATI 4770 and fglrx driver.

Actually, the bug #879156 is related.
I have also noticed that Firefox paints its window title correctly.

The bug doesn't happen on my installation (on intel, but it seems weird it would be video driver dependant)

Bug 781384 I believe is on a related issue, this only happens with fglrx drivers.
