I was working on a little painting program that re-generates a bitmap on every frame, using a PImage object. This seems to cause the sketch to gobble up more and more RAM on each frame, until it runs out of memory and I get an error. Here is an example code that does the same thing but rendering random pixels:

1. PImage img;
   
   void setup(){
     size(250,250);
   }
   
   void draw(){
     newImg();
     image(img,0,0);
   }
   
   void newImg(){
     img = createImage(250,250,ARGB);
     img.loadPixels();
     for(int x = 0; x < img.width; x++){
       for(int y = 0; y < img.height; y++){
         img.pixels[y * img.width + x] = color(random(255));
       }
     }
     img.updatePixels();
   }

If you watch the amount of RAM java is using when this sketch runs it just consumes more and more until it crashes. Any idea of what I can do to fix this?
