I've been having this bug for 2-3 months now and haven't seen anyone else mention it anywhere? Randomly when I'm playing, the lighting will suddenly become much, MUCH brighter and nearly blinding. I can't revert it unless I shut the game down and open it again. It's really annoying. I've attached my dxdiag, and here's a link to a clip of the bug happening: https://youtu.be/uV1rfYhqlaU
