I'm not the OP but I followed up with the observation of different
behaviors depending on how the sexp is evalled.  When I first tested,
I got consistent results, but after reading your post I tried it
again, both with -Q and with my initializations, and now found the
results to be inconsistent, i.e., sometimes I got a fully redrawn
frame and sometimes a blank frame (though when it was blank, moving
the dialog frame did not cause redrawing of the blank frame),
regardless of how I evalled the sexp.  I guess this supports your
suspicion about timing.
