Arcs appear broken in FPS demo.
I'm running the FPS HUD demo in Unity 2020.3.2, and it appears that Arcs don't render when the initial angle is greater than the final angle.
Also, if an arc isn't centered at the origin it appears to have a slightly larger radius than intended.
this has now been fixed in 3.2.2. here are the changes if you want a quick fix before it's released. (line numbers on the left and filename at the top)
