My guess on that is that KWin tends to have more heuristic guesses at 
the right thing to do than I put in metacity. iirc (this was years ago) 
I didn't much try to make things work unless the letter of the spec was 
followed. Didn't want to deal with the endless bugstream about wrong 
guesses. KWin may also have heuristic window state saving unrelated to 
XSMP, e.g. based on window class, for apps that don't support XSMP. Not 
really an endorsement of XSMP when these heuristics kick in, only an 
endorsement of KWin.

It could also just be a bug, or a different interpretation of the letter 
of the spec in any of app, SM, or WM.

Doesn't change the basic point that the best way to fix it is to have 
apps (ideally helped by the toolkit) remember their own window state, 
thus avoiding the whole XSMP Rube Goldberg device. Though scaring the 
chicken into pecking the button that drops the weight etc. may work from 
time to time, it's still a stupid design.
