Something’s not working the way it seems like it should.

When I use the graph max(|ˣ/₈|,|ʸ/₈|) ( \max\left(\left|\frac{x}{8}\right|,\left|\frac{y}{8}\right|\right)=\frac{1}{2} ) and a thickness of 89.9501761685 - 90.0184669925 (with some transparency)

I saw weird circle at the corners

But I expected just a rounded square
