Have you queried the value of 'cex' and related parameters at the different
time points?
The help page for par says that when you set mfcol or mfrow that cex is
changed, but I don't know if the layout function also changes those or not.
I would start by peppering your code with calls to par('cex') to see what
R thinks the parameter is at the time of the different plots. That may
answer your question, or if not at least give up more information to work
with.
