Wierd blocking artifact overlayed onto flash video

[sjs889]

On this page http://sjs889.co.cc/index.php/media/songs there is a playlist for some youtube videos. Using Ubuntu 9.04 Alpha 4 when the playlist is played a black blocking artifact randomly is overlayed onto the flash video.

This is repeatable on all plays.

I notice something similar when playing evony, a flash based game with the adobe plugin

I'm posting in this because it sounds the same as the bug I want to report.
Since Jaunty, embedded youtube videos often have these artefacts flickering through. I'm fairly certain that it is the menu 'showing through', by menu I mean the screen that can be accessed by clicking the up arrow at the bottom right of an embedded video and then the first option which causes the video to shrink and become part of a menu with a youtube search bar, embed and URL link with similar videos at the bottom.
The reason I think that it's this is that I think I can sometimes see the text in part of what flickers into vision, also the flickering stops once the video has been 'shrunk' to form part of that menu.

Managed to get a screenshot, notice visible text.

Has anyone looked at this?
