possibly  
[Unwanted beeping sounds with Vertex functions - #2 by kll](https://discourse.processing.org/t/unwanted-beeping-sounds-with-vertex-functions/9985/2) can help.

* * *

now for the use of the 2 modes:

```auto
function draw() {
  background(); 
  // redraw all again 60 times per sec
}

```

or disabled

```auto
// background();

```

one tip, for showing changing text need to clean up background behind first  
like [p5.js Web Editor](https://editor.p5js.org/kll/sketches/0UmJ7iuox) here.
