I've had users report this as well, yes. For me, with the help of some players I was able to pin-point that it was glow filters causing the issue. I didn't investigate deeper into why, I was trying to be quick so I just removed the glow filters and it seems to have fixed the problem. I have been having a few more reports however that users are still occasionally getting the flickering problem. I'm not sure if its related to more glow filters, or something else though (maybe another filter?).
