I tried all the letters, and didn't see any hangs.

Maybe this only happens in a GTK build with Cairo.

You say "set a large font", but running your recipe I don't see any
large fonts, except in the help-echo tooltips.  Maybe that's why I
cannot see any problems.  Perhaps the problem is with the
set-face-attribute part of the recipe, in that it doesn't produce the
same effect on my system as on yours?
