Is there something wrong with this? This should not change any behavior and simply introduce tracking of the _NET_ACTIVE_WINDOW property that would allow us to properly request window activation and better track focus changes.
I don't think we want to set the HWND as X11 property, particularly since it's not guaranteed to be unique, there can be multiple Wine sessions on the same display.
Eh, right of course... crap.
I'm trying to figure a way to make this work while keeping the logic distributed in every process but to be honest this is the kind of thing that would be much more nicely solved with code in wineserver.
And I don't think delegating it to explorer, as a unique proxy for active window tracking, is strictly equivalent, especially when we will want to request host active window changes.
Would keeping a hwnd / host window mapping in wineserver be acceptable?
You can simply enum the top-level windows and query their whole_window property. It takes a few more server round-trips, but it shouldn't happen that often.
