What we have here is a windowed plugin which we're trying to draw translucent content over. We've never supported that so I'm not sure what happens in FF3.5. This does not work for me in Opera 11.00.

In Chrome, the video is not displayed at all under the translucent toolbar, i.e. it just hides the video completely where there's transparent/translucent content over it. We could do something like that.

Maybe it depends on Windows version or theme for Opera. I'm using Windows 7 with Aero Glass enabled.

The issue is even more obvious on Youtube when opening the feature video list and expanding a video. The video buttons that overlap the playlist can be selected from their position.

Reproducible in Firefox 7 release candidate.

Is this dependent on a particular version of Flash? I cannot reproduce this bug.

I'm still unable to reproduce this on Ubuntu 11.04 64-bit with Flash 10.3.183.10. Is there any other info you can provide so I can reproduce this bug? What is the source of your flash plugin?

Might youtube be serving different content? Specifically if it didn't serve the Flash as a windowed plugin then it would work.

Installed from from http://get.adobe.com/jp/flashplayer/, choose Apt for Ubuntu 10.04+
and also try install from package manager.

Maybe yes. because it works if wmode = Opaque or Transparent.
