The story continues: the above happened with mplayer when I logged in
with compiz-manager as the default wm. With metacity, the textures video
works as long as the whole window is inside the screen. If the window
is partially out of the screen either on the left or the right side, 
it's garbage.
I guess the next version will fix, I saw clipping fixes in the current 
GIT version.
Running compiz-manager in a console to replace metacity, the above
situation occurs again with the difference that the mplayer window
actually appears and is e.g. draggable. But it's empty.
