    I don't know any better way than killing X clients one after the other, possibly using xlsclients etc. to guide you, and testing to see when they are no longer stolen. Usually the prime suspects are the Window Manager and input frameworks, but if it happens both in Gnome and KDE, it might be something else. And yes, FocusIn/Out events mean some other X client is stealing the events.

    dirkt: Thanks, that allowed me to identify the culprit. It was Skype: CTRL-ALT-SHIFT-d activates an extra "Debug" menu item in Skype, and there does not seem to be a way to disable it in Skype. Commented Jun 15, 2018 at 12:38
