I'm still not sure what's going on.  And trying to debug the problem
feels like doing quantum physics where the result changes when being
measured.  In the case at hand the problem does not occur when a
debugger is used.  So this might be related to redisplay.

As a workaround you can use
(add-hook 'find-file-hook (lambda ()
                            (when (eq major-mode 'latex-mode)
                              (TeX-fold-mode 1)
instead of the code you currently use with `LaTeX-mode-hook'.  This
has the additional bonus that you don't need an additional variable as
suggested regarding your problem with Noweb mode.
