This get_window_extent() causes problems on MacOSX. (related to the blitting problems with macosx). You can get around it by calling self.canvas.draw() before get_window_extent(), but that can be laggy. If you check the backend, you can only inflict the lag on macosx users. But then you're putting backend checks into supposedly backend independent widgets.

Any less hacky ideas of how to get the rendered width of a block of text?

l,b,w,h = bbox.bounds

renderer = self.ax.get_renderer_cache()
en = renderer.points_to_pixels(self.text.get_fontsize()) / 2.

r = l + self._cursorpos*np.ceil(en)
r,t = self.ax.transAxes.inverted().transform((r,t))
r,t = self.ax.transAxes.inverted().transform((r,b+h))
return r
