There is a bug I noticed a few months ago that still haven't been fixed - a round glass plane in the back of the Tatuus formula cars in races. It randomly turns on and off, and is very distracting. No other cars have it, only Tatuus DLC. Of course, when I decide to record it for forum, it's not there. But you get the idea. I run mostly high settings, single screen on GTX1060.
