I read it. After some test I can add another example where performEnd
makes a difference:

1) create one shape
2) add a custom effect to the shape (e.g. fade in)
3) add a second custom effect to the shape (e.g. change fill color)
    which is played together with the previous one but it is longer
4) start the animation
5) after one second skip to the next animation (left click)

The final state is the following one:
the shape is wrongly shown with only the first effect applied

I have a problem: I can't hear any sound effect at all.
I got the following message on the standard error:

Message: don't know how to handle audio/x-wav

So I'm not able to perform any test.

Any hint ?
