In the example, the shooting star shows a trail, and the sparkling stars seem to be visible for longer than one frame. Which is good and gives an impression of a night sky.

However, I cannot find any indication in the code that the stars are visible for more than one frame, nor any indication why the trail is visible.

I thought that whatever you show on one frame disappears and is no longer visible on the next trail. Am I missing something?

The area to the right where the sketch draws has suddenly turned to this white square with ‘web broswer’ in the centre and nothing happens when I hit run.
