Either I don't understand your description, or I cannot reproduce what
you describe.  All I see here is expected: Emacs just tries to keep
the frame and the windows at integral multiple of character size.  I
see no other unwarranted resizing.

If that's what you see, you may wish to try setting
frame-resize-pixelwise and maybe also window-resize-pixelwise to
non-nil values, perhaps you will like the results better.

If you see something else, try to describe it in more details, or
perhaps post a screencast.
