I’ve been playing around with [blendmode()](https://p5js.org/reference/#/p5/blendMode) and found it seems to behave different in chrome vs firefox.  
Is this a browser thing or a p5 bug? I’m using latest versions of the browser and win 10 pro.  
Tried it on my desktop and laptop machines. I hear it works on Mac computers.

It seems to freak out when the shadow burn radius is greater than zero.
