I ran a test just now.  I left a window open on the desktop, and also 
started up mythfrontend and started a recording playing.   I then  
<alt-tab>ed to bring the other window to the top. I can move that window 
all over the screen, even above and below the myth video into the black 
area, and the window's contents remain visible. So, yes, myth is drawing 
the black, and too much of it :-)

Doesn't this indicate the problem is within Myth somewhere?

I appreciate the input so far.  What you mentioned above seems to have 
advanced my understanding of the problem anyway.

Yes, it seems all playback is effected.
