I have seen this quirk for years in many pre-GTI inverters. It most often
happens once the bulk charge voltage is reached. You can hear the inverter
buzz fade in and out in time with the light flicker. There are many
different qualities of compact fluorescents, perhaps some with better
filtering. Maybe that's why it occurs on some systems and not others, in
addition to loading differences.
