I’m working on Pde 4 and my Macbook Pro is Catalina 10.15.7  
I found that the basic SPAN tutorial does not work for me

```auto
int x = 0;

void setup() {
  fullScreen(P2D, SPAN);
  background(0);
  noStroke();
  fill(102);
}

void draw() {
  rect(x, height*0.2, 1, height*0.6); 
  x = x + 2;
}

```

I found that I need to delete P2D out and SPAN will work just fine. But in Pde 3.5.4 runs on the same Mac, it works well although threw a long red error but I get the animation as it should.

Any one know the why or if the Pde4 is not a good version yet?  
Thanks
