This is a clear sign that some redisplay optimization is applied when
it shouldn't be.  IOW, Emacs mistakenly thinks the display does not
need to be redrawn.

> However, this is not occurring often, and not reproducible per se -- unluckily.

When that happens next, try typing "M-x".  Just "M-x", without any
command.  If that doesn't help, try "M-x redraw-display RET".

More importantly, post the result of "C-h l" (that's ell, not the
digit one), and try to remember what were you doing immediately before
the incident.  Also, in what mode was the current buffer.
