Comment 3 for bug 879156

What I experience is the following. Sometimes (I cannot really reproduce it since it appears to occur randomly) the either the following happens:
- multiple windows have a window decoration indicating that they have focus.
- or the window that actually has focus is not decorated in as a focused window.

With the default Ubuntu 11.10 theme I recognise a focused window because it has a orange close-button and the window title text is white. I recognise a window that has no focus by a grey close-button and a grey window title text.

When I resize an incorrectly decorated window, then the window decoration becomes what it should be. So it looks like unity does not catch any focus events from the X-server. Maybe this bug is related to https://bugs.launchpad.net/unity/+bug/772777 where a the window title does not get updated.
