It should be gone now in the lastest version.

It seems there was a slight difference between the Flash H.263
and the avi2swf/jpeg2swf H.263 DCT, which allows these small
Y-differences to creep in. (in YUV, (0,0,0) is green, so the
patches where an incorrect Y-value is added appear as green)
I increased the number of keyframes that jpeg2swf generates
that the errors doesn't multiply over such large intervals,
which seems to work for now.
