Try adding some error handling to this line, for example:

  $img->rubthrough(ty=>8, tx=>8, src=>$overlay)
    or die $img->errstr;

Other than that I don't see anything wrong with your code.

If your src image doesn't have an alpha channel, you might want to use
the paste() method instead:

  $dest->paste(left=>8, top=>8, img=>$overlay);

If the above doesn't work, please send me the images involves and
complete sample code that demonstrates the missing output and
I'll have a closer look at it.
