[sugar] video bleeds through somewhat between sessions

[Mikus Grinbergs]

G1G1, Joyride 2241.  In one Terminal session started mplayer -- it 
was playing a movie.  Went to another Terminal session, and entered 
some commands.  Noticed that not all of the text on that screen was 
equally distinct - some of it was paler than others.  Noticed that 
*which* text was paler changed from second to second.  Realized that 
the paler text in the second Terminal screen corresponded to the 
*brightest* areas of the movie frame then being shown in the first 
Terminal screen (the one I had switched way from).
