Why do the `tkinter.ttk.Notebook` tabs get thinner and thinner?

问题

I am using a tkinter.ttk.Notebook and the tabs seem to get thinner with time. How do I overcome this? Is there a possibility to specify a uniform width for each tab?

I use this code to add a tab:

notebook.add(game.frame, text=game.name, underline=0, sticky=tkinter.NS)

I don't know if it's possible to set a uniform width for each tab, but it seems that the tab width problem is style dependent:

• with style "alt" the tab name SEVEN is partially hidden:
• with style "clam" it is fully visible:

Here is how to change style of the whole window:

sty = ttk.Style() 
sty.theme_use(theme_name)

To get the list of all theme names: sty.theme_names().

You can get more information on ttk styles here http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/ttk-theme-layer.html.
