Hello, Alexandre.
Sorry, I was embarassed by the following sentence about the WM_STATE in 
the Inter-Client Communication Conventions Manual, section
"The state field describes the window manager’s idea of the state the 
window is in, which may not
match the client’s idea as expressed in the initial_state field of the 
WM_HINTS property ..."
I thought that "may not" here introduces some ambiguity and allows a 
window manager to distinct these two properties. But now I understand 
that it is indeed quirky to differentiate two and it's rather a defect 
of the window manager than Wine's.
(For your information, I use compiz).
Thanks for your feedback.

Best regards,
