it's an insufficient solution. There are a bazillion of issues which need to be addressed like
* button position order
* geometries of each button (we need to know the position of the close button to recognize a failed attempt to close the window)
* ...

This is just a part of the overall puzzle and I had tried to take it to the NETWM spec list, but hadn't had the momentum to complete the process (after all I have zero interest in fixing behind GTK). It's a lot of work and honestly I think it's a wasted effort as GTK should do the sane thing and disable their decorations on other desktops.

Nevertheless we should make sure that these things will be done properly in the XdgShell for Wayland. Jasper is the main developer of the protocol and I consider him cooperative. I plan to look on the protocol sometime soon and prepare a "KDE view" on it. In my opinion most things missing are related to decorations (e.g. button ordering, etc.). I'll also try to get once again an agreement on that we need to be able to disable decorations completely for convergence. On second thought: it might be better some other KDE dev proposes this not to run into it being ignored because I'm a known opponent of CSD.

For this particular item: if we want to add support we should do it in KWin, but again: I don't care.
