Graphic issues at flood room

[demon0496]

I just made contact with Catherine, and the room floods. After Simon gets up, there are rainbow-like distortions toward the exposed ceiling, and graphic issues in the form of walls appear everywhere. I play on the 2015 Macbook Pro Retina 15" and play on high settings. The game has played beautifully up till this point, but when this event occurs, everything goes haywire. I've tried changing the shadows, refraction, and refraction, but nothing changes.
*I've tried uploading my hpl.log but the attachments aren't working. I tried changing it to a attaching a hpl.zip, but that doesn't work either*
