I had inexplicable crashes when using textures on PShapes that almost made me loose my will to live until I finally found the cause:
If I create a PShape in "noStroke" state, setTexture will work the first time, but when I then try to set a different texture and redraw, it'll crash:

 PShape shape; void settings() { size(400, 400, P2D); } void setup() { } void draw() { noStroke(); // Remove this, no crash shape = createShape(RECT, 0, 0, 200, 200); PImage p1 = loadImage("img1.png"); shape.setTexture(p1); shape(shape); PImage p2 = loadImage("img2.png"); // p2 needs to be a different size from p1 shape.setTexture(p2); shape(shape); // Crash! } 

It's an ArrayIndexOutofBoundsException in PShapeOpenGL, line 843, because the field "firstLineVertex" happens to be -1...
