<p dir="auto">I see modal flicker on iPad Retina in Safari and in Chrome 29.0.1547.57 on OS X 10.7.5. This needs more testing, please. Thanks!</p>
<p dir="auto">When launching the modal component (<a href="http://getbootstrap.com/javascript/#modals" rel="nofollow">http://getbootstrap.com/javascript/#modals</a>) the entire content will slightly move to the left on mac OS (haven't tried it on windows yet). With the active modal the scrollbar seem to disappear, while the content width still changes.</p>
<p dir="auto">You can observer the problem on the bootstrap page</p>
