Like many things, just an option change away - ccsm -> scale ->
multioutput_mode = "On current output device"

But this option spreads *all* windows in the current device, doesn't it? Not in their respective monitor like this bug is about.

Sam, multioutput_mode = "On all output devices"

gets this to work for me.

As of today with all updates and compiz 0.9.7.6 the spread/maximize/enlarge on a multimonitor setup with each screen having a different resolution is still broken in the following way.

It will always enlarge/spread/maximize to the biggest screen although the window position and the maximize action was initiated from the smaller screen, in the condition that the window that is subjected to enlarging has a "vertical" and or "horizontal" resolution that is larger than the resolution of the smaller screen! Eventhough the orange opacity grid (related to the maximize/enlarge/spread activity) lifts up on the first smaller screen where it was initiated but the window it self appears on the other second larger screen maximized.
