Research direction
Start by loading the linked OpenProcessing sketch and comparing blendMode() in Chrome and Firefox on Windows 10, using the reported p5.js 1.0.0 and browser versions. Then inspect the Core/Environment/Rendering area for blendMode handling. Done means the sketch renders consistently when changing blend modes in Firefox and Chrome on Windows.
