title: WMODE and Flash Video - stability and performance
body: <p>for a business reasons I need to overly Flash video player with HTML content. This requires the WMODE to be set as "opaque". </p>
  
  <p>However Flash Player Engineering Tinic Uro warns us over <a href="http://www.kaourantin.net/2010/02/core-animation.html" rel="noreferrer">lower performance</a> and couple years ago he even mentioned <a href="http://www.kaourantin.net/2005/01/wmode-and-flash-video.html" rel="noreferrer">serious instability</a> and Adobe <a href="http://kb2.adobe.com/cps/155/tn_15523.html" rel="noreferrer">TechNote 15523</a> states "<em>the WMODE parameter is supported only on some browser/Flash Player version combinations</em>".</p>
  
  <p>In addition there is whole bunch of bugs associated directly with the WMODE option (search for "wmode" and "opaque" in <a href="https://bugs.adobe.com/jira/secure/IssueNavigator.jspa" rel="noreferrer">Adobe Flash Player Bug and Issue Management System</a>)</p>
  
  <p>To my knowledge even YouTube tries to avoid using the WMODE "opaque" at any cost, just have a look at the design of the account drop down menu above expanded video.</p>
  
  <p><strong>My question is:</strong> </p>
  
  <p>Do you have any experience with lower performance, bugs or instability regarding Flash video and WMODE "opaque"? Can you share any good reading on this topic?</p>
