And a working code I've got here w/ me:
    // http://forum.processing.org/topic/pdf-export-shapes-misaligned
    
    import processing.pdf.*;
    
    final static boolean RECORD = true;
    
    final static int DIAM = 300;
    final static int STEP_X = 15, STEP_Y = 15;
    
    final static float FRACT = 1.15;
    
    final static color BG = #556270;
    
    final color[] palette = {
      #4ECDC4, #C7F464, #FF6B6B, #C44D58
    };
    
    void setup() {
      size(960, 645);
      noLoop();
    
      initialize();   // initializes main canvas setup
    }
    
    void draw() {
      if (RECORD) {
        final String path = dataPath("frame-####.pdf");
        beginRecord(PDF, path);
    
        initialize(); // initializes PDF's own graphics setup
      }
    
      background (BG);
    
      final int xx = width;
      final int yy = height + DIAM;
    
      for (int y = STEP_Y; y < yy; y += DIAM + STEP_Y) {
        for (int x = STEP_X; x < xx; x += DIAM + STEP_X) {
          drawCircle(x, y, DIAM);
        }
      }
    
      if (RECORD) {
        endRecord();
        println("Frame: #" + frameCount);
      }
    }
    
    void mouseClicked() {
      redraw();
    }
    
    void drawCircle(int x, int y, float d) {
      fill(palette[(int) random(palette.length)]);
      ellipse(x, y, d, d);
    
      if (d > 2) {
        drawCircle(x, y, d/FRACT);
      }
    }
    
    void initialize() {
      smooth();
      noStroke();
      ellipseMode(CORNER);
    }
