Hello,

This has to do with the default pixelDensity() for each device:

[https://p5js.org/reference/#/p5/pixelDensity](https://p5js.org/reference/#/p5/pixelDensity)  
[https://p5js.org/reference/#/p5/pixels](https://p5js.org/reference/#/p5/pixels)

I get the same results as you do on the same device with this (one of them) added to setup() :

```auto
 pixelDensity(1); //Shows 1 fractal
 pixelDensity(2); //Shows 2 fractals

```

I first came across this issue with this example and had to set it:

> Hello, I changed topic to p5.js category. See example here: Example may be a bit complicated (moving tiles) but I had to sort out color for pixels[] and learned this recently. References: [https://p5js.org/reference/#/p5.Image/pixels](https://p5js.org/reference/#/p5.Image/pixels) Have fun! slight_smile
