Firefox vs. Chrome: CanvasAuthor: Jacob Barkdull on Sunday, July 21 2013 Comments ↴
I just reported this bug to Google. It's a (should be) simple HTML5 canvas element drawing of multiple overlaying translucent rgba color rectangles. In Firefox it's perfect, in Chrome preceding canvas draws become more and more transparent with each additional rectangle.
Top: Firefox 22.0
Bottom: Chrome 28.0.1500.71
Test it yourself.
