Could be, but it seems rather unlikely.

This code should be pretty much 100% platform independent.
So, please do M-x ielm
and then in this read-eval-print interactive loop, make sure
overwrite-mode is not nil, and then play around with

  (format-mode-line minor-mode-alist)

e.g. start with

  (format-mode-line '((overwrite-mode overwrite-mode)))

and if this one returns " Ovwrt" as it should, then add elements from
minor-mode-alist little by little (ideally, using a bisection-search, aka
binary-search) until you find what gets in the way.
