Processing P3D Animation leaving artifacts behind

问题

I am trying to make a spinning cube in Processing's P3D with this code:

int sizes = 500;
int rotation = 0;

void setup() {
  size(500, 500, P3D);
}

void draw() {
  lights();
  translate(sizes/2, sizes/2, 0);
  rotateY(rotation * (PI/180));
  rotateX(rotation * (PI/180));
  background(0);
  box(sizes/2);
  rotation = (rotation + 1);
}

When I run it the cube does spin as I wanted, but there are strange 'artifacts' (for lack of a better name) left behind its edges.

What causes this issue, and can it be solved?
