"Sometimes"? Can it be that it happens when Emacs needs to display
some character not available in the "non-ugly" font?

??? Incredible. You mean, you do all that magic, and the font used
for some text suddenly changes? Without killing the buffer with that
text?

Put a breakpoint where Emacs loads new fonts, and see who calls that
code.
