Public bug reported:

Windows sometimes randomly resize themselves. Often, a maximized window
will go rapidly between maximized and unmaximized states - as much as a
few times per second. This happens both with windows that have focus and
windows that do not have focus. However, unfocused windows that randomly
resize themselves seem to take focus away from the current window.
Another problem which is perhaps related is that the orange window
frame, which Unity uses when placing a window in a corner or against the
edge of the screen, randomly appears and does not go away until one
grabs a different window and drags it to the edge of the screen. A
screen grab of this happening is attached.
