If there is a canvas element on the page with width and height larger than 71, text anywhere on the page will lose rasterization fidelity when the canvas API is used. This problem exists in the current public version of Chrome as well, but the magic number there is 256x256. Here are jsfiddles demonstrating the problem: canvas size below threshold, scaled text looks good: http://jsfiddle.net/AQk5z/2/ canvas size above threshold, scaled text looks bad after using canvas API: http://jsfiddle.net/BxrXk/1/
