The code below should(?) display a red circle moving over a black background but the red background is not masked.

Problem occurs in 2.0b8 on Windows7 with up to date graphics drivers.

This code has been reported as working on 1.5.1. on osX 10.8

//begin code

PGraphics maskGraphic; PGraphics displayGraphic;

void setup() { size(1000, 600, P2D); maskGraphic = createGraphics(1000, 600, P2D); displayGraphic = createGraphics(1000, 600, P2D); }

void draw() { background(0);

maskGraphic.beginDraw(); maskGraphic.background(0); maskGraphic.noStroke(); maskGraphic.fill(255); maskGraphic.ellipse(mouseX, mouseY, 300, 300); maskGraphic.endDraw();

displayGraphic.beginDraw(); displayGraphic.background(255, 0, 0);
displayGraphic.endDraw();

displayGraphic.mask(maskGraphic);

image(displayGraphic, 0, 0); }

This is a bug report for processing/processing, not processing/processing-web. Please report it there.

It looks like this is a repeat of processing/processing#1738
