I'm having trouble creating a simple example where I cover a background image with a solid color and the user is able to use the mouse cursor to click and hold to "erase" the foreground color to expose the image behind it. I'm using a mask to cover the image and the Graphics module to draw circles with alpha transparency to expose the image underneath. The issue I'm having is after a certain number of circles are drawn, Pixi just stops drawing anymore. I would appreciate if someone could help me
