I haven't had a chance to test the issue yet.  In the latest OSG there are
rewrites of various parts of the OSG to move fully over to use vertex
arrays and supporting VAO's, my guess is this work touched upon
osgSim::LightPoint* functionality and introduced a regression, as to what
this might be I can't say without reproduce the issue and investigating the
related code.

In general the behaviour you describe sounds like vertex array state that
is not being set up correctly so the values used by the driver are just the
last ones to be set rather than the one intended.
