On a recent ubuntu linux with the gtkagg backend, there appears to be a one pixel error in animation blitting. Eg, see dynamic_image.py at

http://github.com/dopplershift/Animation/tree/master/examples/

I doubt this has to do with Ryan's package as he just uses blit, so it is probably a bug in mpl (using 1.0.0svn)
