i also have a lot of canvas-heavy code and use typed arrays pretty extensively. i think that mozilla's canvas implementation is actually the bottleneck here, not the JS. chrome's canvas proves to be much faster, though.

  That issue is basically fixed in most sane code, actually; I just resolved it as such. For example, on http://jsperf.com/pixel-pre-rendering/5 http://jsperf.com/pixel-pre-rendering/5 I see identical numbers for the two versions of the test.

      If there's a testcase showing the problem, please file bugs! Doesn't need to be minimal or anything, just a link to the page showing the problem.
