Unity: unmaximize puts window in the wrong position, and titlebar + window control buttons become unresponsive

[GonzO]

To replicate:

1) Log into unity.
2) Open Nautilus.
3) Maximize Nautilus (either by double-clicking the title bar or using the button)
4) Unmaximize naitlus (either by double-clicking the title bar or using the button)

Expected behavior: Nautilus returns to the same size and position it was at before, and the title bar and its buttons continue to function

Actual behavior: Nautilus returns to the same size, but not the same position... it is placed a title bar's height lower than it used to be, and the title bar is completely non-responsive to any mouse interaction. I can't click it, drag the window to a new position, or use any of the buttons -- they do not highlight or respond to clicks.

Keyboard controls still work (CTRL + SUPER + UP/DOWN), but with every unmaximization, the window gets placed 1 titlebar's height further down the screen, and the titlebar and buttons never work again until the program is killed (which I have to do in the launcher or with the pull-downs) and restarted.

This makes Unity borderline unusable for me, and only started very recently.

NOTES: This happens with nVidia and Nouveau drivers. This also occurs right off of the LiveUSB. I'm thinking a recent change really did something wrong here.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This particular bug has already been reported and is a duplicate of bug 1158161, so it is being marked as such. Please look at the other bug report to see if there is any missing information that you can provide, or to see if there is a workaround for the bug. Additionally, any further discussion regarding the bug should occur in the other report. Feel free to continue to report any other bugs you may find.

Also please report a new bug about the second problem (window not restoring to original position) if it still persists after fix for bug 1158161 is released. Right now I believe both problems are caused by the same bug (i.e. compiz doesn't remember that the window has a titlebar and doesn't adjust the window location accordingly)
