probably it depends on the speed of the machine. With an old and slow
laptop of mine the flickering effect appears to be a bit worse than on my
desktop machine. Changing only the padx by one pixel seems to cause only
a slightly "trembling" effect that is hardly noticable at all, so I guess
the second workaround might be a bit better. (Maybe calling those
workarounds "stupid" the other day was a bit harsh, if there's actually
nothing better the second version might be not so bad)

Still I am not sure if I didn't miss something here. I think one bad
thing about ttk is that the more advanced operations on styles and themes
aren't really documented very well, so I always find it hard to find out
how to do things properly, I always end up with some try-and-error
solution.

Best regards

Michael
