1. void setup() {
2.   size(400, 400, P2D);
3.   noSmooth();
4. }
5. void draw() {
6.   background(30);
7.   noFill();
8.   stroke(255, 70);
9.   for (int i=0; i<width; i+=10) {
10.     for (int j=0; j<height; j+=10) {
11.       point(i, j);
12.     }
13.   }
14. }

Running the code above, nothing shows up on the screen, just the dark grey background.

When I remove P2D, and render with the default renderer, everything looks fine, BUT, when I export that to application(mac os x), the dot grid is all broken apart.

What's more strange is that when I compare the result of the same program running in Processing IDE and MacOSX application,

1. background(30);

the background value is 40 in P5 IDE whereas Mac Application renders the color correctly.

Anybody has seen this happening?
