I had this problem back in the first beta, and made a post about it then, but it has since been deleted. But, I’ll post it here again with some more information, just in case it can still help. My graphics card is a Radeon RX 570 Series.
The problem is that reflective surfaces, such as metal or water (The water is the most extreme) tend to have this sort of flicker on them. On this first video, you can see it primarily on the left.
On this second, it’s just all over the ground. Though, note the weird square thing going on on the right. Strange dark squares seem to be fairly common with this.
And finally, here are the console and launcher logs.

I’ve tried changing just about every setting I can to no avail. But, I remember the first post I made of this, another guy mentioned he had a 560 or 580 series and had the same problems. Both of those have made me guess it might be the cards themselves. I’m not really a tech guy, so I don’t know if that is true, or if that means it can even be fixed on Fatsharks end.
Hopefully all that helps and you can narrow it down.
