Currently the keymapnotify event handling is commented out as FIXME in SDL_x11events.c (It looks like this may have functioned SDL1.2).
Not handling this event means that if a window manager shortcut such as ALT+SPACE is used, SDL will send an ALT key down signal, but not an up signal. Also querying SDL about the key state, it believes the ALT key remains pressed.
X passes the events keypress (alt), ?focusout?, ?focusin?, keymapnotify.
