presently updating drivers... (and everything else ;) )

[UDPATE]

No impact.

However, I have noticed that launching the game from a different directory had the effect of correcting the bug, so I think it's a config issue, or it's something to do with ironwail.pak

Identified the difference: vid_fsaamode 1 causes the dynamic lights to appear fractured

This is a driver bug, if you're using open-source drivers please try the proprietary ones (and vice-versa). vid_fsaamode is literally a single GL state (glMinSampleShading), and I've tested it on NVidia (GTX 1060, Windows & Ubuntu), AMD (HD 7850, Windows & Ubuntu) and Intel (Atom x7-Z8700, Windows) and it works as expected.
