I tried on 2 computers, both with gentoo. one 64bit with mpl 0.98.5.3 and wxwidget 2.8.10.1 another with mpl svn rev 7249 and wxwidget 2.8.10 and it 'twinkle', the lines are not drawn each frame. I recorded a small video which I put on rapidshare (couldn't think of anything better for now) : http://rapidshare.com/files/253966760/anim-twinkle-mpl-wxgtk.mpeg.html that shows the plot twinkling
it twinkles way more 'live', the video is only 30 fps If you (and no one else?) gets that, I guess the problem comes from my install, somewhere.
