I'm guessing, but did you try changing the (Tk) ``highlightthickness``?
E.g., something like:

widget.config(borderwidth=0, highlightthickness=0)

It's a moderately classic Tkinter gotcha.  You remove all the borders and
there's still one (hightlightthickness) still there, but it only shows up
when you interact with the Frame.

Hope that helps,
