Thanks,
I also noticed a similar dual lighting problem with the Linux open source Radeon driver that's not present in the AMD one, this might be a similar driver bug.
Or I'm doing something wrong, but Mesa renders it correctly and at the moment I've taken the rule 'if mesa renders it correctly, glitches on other platforms are most likely driver bugs', based on Travis' side notes.
Anyway thanks again.
