The last time I played was on the Devlog #6, I play on PC, I don't know if there is a specific line, but it always happens when Helios first appears, I haven't saw if it stops at some point, since it really bothers my eyes, but I wanted to make a video about it, and since I can't find any videos of the new demo, it is sad though, I can't make it, but I hope you are able to fix the bug.
Verywell, bye!
Again, english is not my firdt language
