If, with xfwm4, you maximise a window, then try to drag it by the title bar, it will pull away from its position, but remain the same size, and remain in a 'maximised' state (indicated by the button in the titlebar). If you try to unmaximise this window, it jumps back to the position it was in before it was initially maximised. This is particularly annoying when you try to drag a maximised window between Xinerama screens.

I think the best behaviour for this is done by metacity: When you try to drag the titlebar, initially nothing happens, but when you drag more than a certain distance from the top of the screen, the window changes to an unmaximised state, where you can drag it around. If you then drag it back near the top of the screen, it returns to a maximised state (this is particularly useful if you drag a maximised window to near the top of another Xinerama screen - it becomes maximised on that screen). (Note: if you drag a non-maximised window near to the top of the screen, it has no effect)

Reproducible: Always

Steps to Reproduce:
1. Maximise a window.
2. Drag it away from its position.

Actual Results:  
Window moves, yet remains in a maximised state.

Expected Results:  
Window should move and become unmaximised.
