actually it was a bug in the dispersion code (it was kicking in when it
should not have).

this is because display gamma correction is on by default in 3.7, and your
scene is designed for no correction. add a #version 3.6 or assumed_gamma 2.2
to your scene to avoid this issue (though it is better to change the scene to
look correct with gamma correction on since it will be more portable).
see the release notes for more information on the way gamma works now.
