MathJax reloads with each refresh, so
it's going to hop. There's no way around this, except to disable
math while previewing.</p>
<p>2) If not using math, adjust the preview delay to find a value
that works for your machine/document style. You can also set it to
only update the preview when you save, giving you manual control
over the refresh rate. You can trade responsiveness for
smoothness</p>
<p>Having a truly live preview requires frequent refreshes of the
HTML content in the preview. Unfortunately, Apple's webkit API
somewhat limits ones ability to modify the HTML, instead requiring
a complete reload. Similarly, the algorithms used to keep the HTML
lined up with the text will occasionally "misfire."</p>
<p>Composer's preview is the fastest I have seen (test using long
documents to see the difference in performance), and is the only
one I have seen that accurately keeps both panes lined up (other
apps use a % from the top algorithm, which only works in quite
basic documents).</p>
<p>I also wish that Apple's Webkit did a better job with this, and
I continue to look for other tricks to work around the
limitations.</p>
<p>Thanks for using Composer, and thanks for writing in!</p>

between continuous preview and on-save preview. I've switched, am
happy, many thanks!</p></div>rsiegletag:support.multimarkdown.com,2013-02-12:Comment/314772262014-02-08T23:34:31Z2014-02-08T23:34:31Zjumpy preview pane<div><p>You're quite welcome!</p></div>Fletcher
