If anyone has a suggestion for a cleaner non-invasive change, it would
be welcome. I'm also agreeable to postphoning this bugfix till after
the release, if it is considered unsafe.

It's still unclear, from the messages you sent, whether this bug can
happen outside of HAVE_WINDOW_SYSTEM. The bugfix is meant to plug a
loophole in the code in note_mouse_highlight that computes whether or
not the mouse highlight has been updated, which is only present for
HAVE_WINDOW_SYSTEM. (It is possible to change note_mouse_highlight
itself, e.g. by introducing dpyinfo->mouse_face_buffer. This turns
out, however, to be a fairly intricate change.)
