While in an ediff-buffers session, I executed M-x make-frame to get a new
window. That newly created window did not have the correct font set (it
used Adobe Courier while I have the default face customized to use the
Terminus font).
M-x customize-face default showed it as "SAVED and set" with courier as
the font family. "Reset to saved settings" caused both frames to be
repainted, using the correct font.
Another M-x make-frame once again used the wrong font, so it seems
something goes wrong during frame creation causing new frames to get an
incorrectly set default face.
