[nouveau] Totem playback using X11/Xshm/Xv is erratic in background

Using the Live image for QA test day 2009-03-26, as prepared on 2009-03-25. Totem works great in the foreground, but behind a Firefox window produces erratic video. As the foreground Firefox window is moved over the Totem window, it looks as if the video is "resizing" inside its container widget, in a manner of speaking, but the output is unintelligible. When the Totem window is brought back to the foreground, the output immediately becomes clear and correct again.
The problem also appears when *more than one window* like a GNOME Terminal is placed in the foreground over the Totem window. Firefox triggers the problem by itself every time. A lone GNOME Terminal window does not trigger the problem.
Some screenshots illustrating can be found here:
I'll attach them to the bug if that's more appropriate.
I can confirm this issue as well. I also get the same graphical corruption when dragging the video window 1/2 off the screen to the left or right.
This is probably a duplicate of what I saw, Bug 492227.
I found that if I didn't cover the video from top to bottom with the new window, it didn't fail. Ie. If I only covered a the video with with a corner of another window it didn't fail.
Agreed, marking as dupe.
