This is going to be a controversal change. It enforces KWin decorations on all client side decorated windows from GTK+. Unfortunately we are caught between a rock and a hard place. Keeping the status quo means having broken windows and a more or less broken window manager due to GTK+ including the shadow in the windows. This is no solution. Enforcing server side decorations visually breaks the windows. This is also no solution. So why do it? It's our task to provide the best possible user experience and KWin is a window manager which has always done great efforts to fix misbehaving windows. One can think of the focus stealing prevention, the window rules and lately the scripts. The best possible window management experience is our aim. This means we cannot leave the users with the broken windows from GTK. The issues we noticed were reported to GTK+ about 2 months ago and we are working on improving the situation. Unfortunately several issues are not yet addressed and others will only be addressed in the next GTK+ release. We are working on improving the NETWM spec (see [1]) to ensure that the client side decorated windows are not in a broken state. This means the enforcment is a temporary solution and will be re-evaluated with the next GTK release. I would prefer to not have to do such a change, if some of the bugs were fixed or GTK+ would not use client-side-decos on wms not yet supporting those all of this would be a no issue. For a complete list of the problems caused by GTK's decos see bug [2] and the linked bug reports from there. The change is done in a least inversive way in KWin. We just check for the property _GTK_FRAME_EXTENTS and create a Q_PROPERTY in Client for it. If we add support for the frame extents in future we would also need this. So it's not a change just for enforcing the decoration. The actual enforcing is done through a KWin script so users can still disable it.
