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/ 605674 1 jason 2012-04-19 10:34:05 -0700 Sorry, pasted the wrong fiddles: > canvas size below threshold, scaled text looks good: http://jsfiddle.net/AQk5z/2/ below threshold: http://jsfiddle.net/AQk5z/3/ > canvas size above threshold, scaled text looks bad after using canvas API: http://jsfiddle.net/BxrXk/1/ above threshold: http://jsfiddle.net/BxrXk/2/ 605738 2 simon.fraser 2012-04-19 11:32:15 -0700 *** This bug has been marked as a duplicate of bug 23364 ***
