Hello this is been happening to me quite a bit lately. When I played destiny the shadows will just disappear and the room gets very bright, I thought it was an HDR issue so I turned it off it's still doing it. As an epileptic there's a few times this is almost caused me to have a seizure. Hopefully this can get figured out. This has been happening a lot lately it is not just this encounter. It happens in many instances in destiny 2. I have a video, if needed there are two more I've uploaded as well that I can share. Thank you for taking your time and reading.
