I can confirm this bug with Marco/MATE. A regression test yields:

zeb at terabithia:/bridge/git/wine$ git bisect good
c5ec1585f6e5211a2b63e3435748210552250534 is the first bad commit

    winex11.drv: Always update _NET_WM_STATE in update_net_wm_states().

    KWin treats a window covering exactly the whole monitor as maximized
    when handling its first map request and expects applications to update
    maximized state later. Wine doesn't know about this added maximized
    state and expect it unchanged, making the window always maximized
    as far as KWin is concerned. So always send _NET_WM_STATE updates
    even if Wine doesn't expect changes to hint KWin that a window should
    not be maximized.

    Fix test failures when running the tests introduced by
    36b720357bcaf0a1e625f488e0c981ce10e8affa with KWin.

Zhiyi, would you mind taking a look at this?
