I mean, here's how idosyncratic and poorly understood this problem is: I get photosensitive problems. Didn't trigger for me enough for me to notice it, didn't trigger for our alpha testers who have photosensitivity problems, so I'm guessing that we accidentally have an alpha test pool of people who are skewed to one particular photosensitivity trigger and the people who are reacting are ones with one of the other ones.
