After maximizing window, dragging title bar of different window moves maximized window instead

[Captain Chaos]

Binary package hint: metacity

Whenever I maximize a window by double clicking on the title bar, if I then try to move a different window by dragging the title bar, the maximized window is moved instead.

It doesn't happen if I maximize the window by clicking on the maximize button in the title bar, only when I double click the title bar.

I can prevent it from happening by clicking on another window after having maximized the first window, but this triggers another, presumably related bug (possibly even the underlying cause of this bug):

When I maximize a window by double clicking on the title bar, and then click on the title bar of another window, the focus is transfered back to the maximized window! I have to click on the other window *again* to give it focus. This only happens when I click on the title bar of the other window, not when I click on the client area of the window.

Have the same problem - just didn't realise it came from maximising with a double click on the title bar.

I guess that is why it only happened sometimes, but not always...

But using your description (open a window, maximise by double click on title bar, open another window which is now in front of the maximised window, trying to click the other window "clicks through" it and onto the maximised window, bringing it to the front instead), I can safely reproduce this behaviour on my machine (Lucid Lynx RC).

It doesn't really click through to the maximised window underneath. I can reproduce the bug on a dual monitor system, when moving a window on a different screen to the maximised one. The windows don't need to overlap to reproduce the bug.

I've had this bug for a few months. Running 9.10. I would suspect that some update came through to introduce the strange behaviour.

Also affects me on Lucid, i686, since about 1-2 months.
