--- Comment #16 from Michal Suchanek hramrach@gmail.com 2012-05-03 07:06:43 CDT --- I will believe that my WM sends bogus data in KeymapNotify when I see it logged and decoded and the actual bug showing there.
Also AFAIK the keymap notify is sent by X, not WM, so the WM is pretty much irrelevant here.
