Screenshot of malfunction/distortion

Description of problem:
The graphics of some flash content is distorted by random white rectangles in Firefox 4 with Adobe Flash plugin. I tried both 32bit with nspluginwrapper and native 64bit "Square" version.
See attached screenshot which is related to http://www.wolfram.com/broadcast/screencasts/mathematicabasics/ and have a look at http://www.pixeloptics.com/ where the distortion also appears.

Version-Release number of selected component (if applicable):
Flash 10.3 d162 (64bit "Square" OR 32bit with nspluginwrapper)
Firefox 4.0-0.19.rc1.fc15

Steps to Reproduce:
1. go to http://www.wolfram.com/broadcast/screencasts/mathematicabasics/
2. start video, if it doesn't automatically
3.
  
Actual results:
Flash content flickering of white rectangles.

Expected results: Just smooth video playback.

Additional info:
On same system with google-chrome-stable (using same flash plugin), this issue does not occur. Other users on Fedora 14 with different Firefox 4 builds don't have this issue. So it must be a problem with this Firefox 4-Package!

Unfortunately, the issue here happened in the binary-only flash player for which we don't have any source code, so unfortunately we cannot help you with it.



Closing as CANTFIX (because that's our situation)

But since this problem does only occur when combining a 64bit-Kernel, Firefox 4 and Gnome 3, you can't blame the flashplugin only. Other users with Fedora 15, 64bit with Fluxbox and Firefox 4 report, that those errors don't appear, and I myself can confirm, that these errors don't appear when using Google Chrome but leaving the rest of my system untouched!
