--- Comment #5 from Roc Vallès i Domènech rvalles@es.gnu.org 2007-12-30 18:59:13 --- To "last frame's image remains" I add "instead of showing a background picture".
Background begins being white and then basically shows whatever it had last been overwritten with.
To me it looks like the real problem is that the background picture doesn't get to appear (which is too bad, since it's pretty), and the problem we see derives from that.
