Line/stroke fading issue

Hi All

I recently went from using Processing 1.5.1 to 2.0 Beta 3 and have found a quirk in the P3D drawing.

I'm trying to leave trails when drawing graphics by not calling background() but drawing a low alpha rect() at the beginning of each draw function. This is a technique I've used many times without a problem but I'm finding that lines or ellipses/rects with strokes are not fading.

If you change the renderer to P2D this isn't a problem. The speed of P3D is required for this project.

Am I missing something? Are others finding the same issue?

2. void setup()
3. {
4. size(500, 500, P3D);
5. }
7. void draw()
8. {
9. pushMatrix();
10. //translate(200, 0, 1);
11. fill(222, 1);
12. rect(0, 0, width, height);
13. popMatrix();
15. fill(random(255), 24, 76);
16. ellipse(random(width), random(width), 30, 30);
17. line(random(width*0.5), random(height*0.5), random(width*0.5), random(height*0.5));
18. }
