RadioBox text is "clipped" on OSX (wxpy 3.0.2)

I have a radiobox selection control, that is
placed on a SizedControl.Panel, and the end of the text is clipped
(not rendered properly).

  The text was ok with wxpy-2.8.12.1 (Carbon), but is corrupted with

wxpy-3.0.2 (Cocoa).

  If I had 4 extra spaces to the end of the text, then I can get it

to display the text properly (but the control is a little wider).

  See the image at this link.

  Any idea how to fix this?

  What has changed in wxpy-3.0.2?  Or is it a Cocoa issue?
