I could reproduce this by changing the value of the variable
`w3m-toolbar-configurations'.  The default value for GTK is:

'((tool-bar-button-margin . global))

It means the real value of `tool-bar-button-margin' in the *w3m*
buffer is derived from the global value, i.e., the one in another
Emacs buffer.  It doesn't cause the frame height jumping in my
system, but I tried changing the value to

'((tool-bar-button-margin . 10))

and could reproduce it.  I could also reproduce it by using the
big icons, which are in the icons30/ directory in the emacs-w3m
trunk.

There will be two ways to solve the problem.  If the emacs-w3m
icons are smaller than the ones that Emacs uses, try customizing
the `w3m-toolbar-configurations' variable into the suitable value.
For example:

(setq w3m-toolbar-configurations
      '((tool-bar-button-margin . 10)))

If the emacs-w3m icons are bigger than the ones that Emacs uses,
You will need to customize both `w3m-toolbar-configurations' and
the global value of `tool-bar-button-margin'.
For example:

(setq tool-bar-button-margin 7
      w3m-toolbar-configurations
      '((tool-bar-button-margin . 1)))
