<p dir="auto">I've noticed that when opening/closing a modal box causes a little flicker on Chrome, so I realized that the cause of that is the next couple of lines in the CSS stylesheet for the .modal.fade .modal-dialog:</p>
<div class="highlight highlight-source-css notranslate position-relative overflow-auto" dir="auto" data-snippet-clipboard-copy-content=" -webkit-transition: -webkit-transform 0.3s ease-out;
     -moz-transition: -moz-transform 0.3s ease-out;
       -o-transition: -o-transform 0.3s ease-out;
          transition: transform 0.3s ease-out;"><pre class="notranslate"> <span class="pl-c1">-webkit-transition</span><span class="pl-kos">:</span> -webkit-transform <span class="pl-c1">0.3<span class="pl-smi">s</span></span> ease-out;
     <span class="pl-c1">-moz-transition</span><span class="pl-kos">:</span> -moz-transform <span class="pl-c1">0.3<span class="pl-smi">s</span></span> ease-out;
       <span class="pl-c1">-o-transition</span><span class="pl-kos">:</span> -o-transform <span class="pl-c1">0.3<span class="pl-smi">s</span></span> ease-out;
          <span class="pl-c1">transition</span><span class="pl-kos">:</span> transform <span class="pl-c1">0.3<span class="pl-smi">s</span></span> ease-out;</pre></div>
<p dir="auto">This issue has been bouncing around a bit; basically, on my modal dialogs, I see a bit of "flicker" (the content rapidly appearing/disappearing) when hiding or unhiding the dialog.</p>
<p dir="auto">I was able to capture some of it in a screen capture:</p>
<p dir="auto"><a href="https://vimeo.com/73808307" rel="nofollow">https://vimeo.com/73808307</a></p>
<p dir="auto">It is most visible when closing the dialog.</p>
<p dir="auto">This is on Mac 10.7.5 and Chrome 29.0.1547.65.</p>
