No, they shouldn't, and as far as I can tell, they don't. I added debug statements to the place in KDE libraries for sending this message and it's not called when the problem occurs (and Qt does not use _NET_ACTIVE_WINDOW at all). Also, I can reproduce the problem even in KDE, but only with Metacity running instead of KWin, which narrows it down to the offender being either Metacity or KCalc (+libs). Since the request doesn't seem to come from KCalc and KWin should have the same problem if it did, I think the problem is in Metacity. I suggest you try to find out where the activation request really comes from. > The bug is http://bugzilla.gnome.org/show_bug.cgi?id=445835 -- the reason > for the title is that metacity sets _NET_WM_STATE_DEMANDS_ATTENTION for at > least partially obscured windows which attempt to activate themselves (and > ignores the request). > > (Of course, this is not a kwin problem, but the people on #kde-devel said > to come and ask here because you would be most likely to know.)
