It's probably some bad interaction between compositions and the
handling of faces in the bidirectional display.  Perhaps Handa-san
could take a look at xdisp.c:handle_stop_backwards and how it is
called inside next_element_from_buffer -- there might be some bugs
there whereby only part of the composed sequence is redrawn when the
region is extended or contracted.

This one is your problem: you should never do that on MS-Windows.

These are obsolete, as everything is always unified in Emacs 24.
