I can confirm that with Feisty final, compiz activated, Radeon 9800 Pro with 'ati' driver (details at the bottom).
It does not seem to depend on any compiz setting.

When opening a window and then maximizing it, the title bar buttons do not work anymore.
After pressing Alt + leftclick in the window (activating the "move window" mode), the buttons work again.
When unmaximizing from this state, the title bar buttons stop working in the now unmaximized window until briefly activating the "move window" mode.

When a window is opened in the maximized state, same behaviour after unmaximizing once.

When the title bar is in the 'broken' state, right clicking on it displays the desktop popup menu, or if there is another window at that position, brings that window to the foreground. It's as if the title bar did not exist (see screenshot, note the context menu, I right clicked directly on the title bar, then waited for the delayed screenshot to be taken).

This happens to me almost every time, but not *every* time.
