In miui rom this problem is imperceptible, since the screens in the edges are cropped flawlessly. while in this rom in any screen you notice that the edges are cropped badly compared to the original miui rom. a careful eye notices it immediately, which is why unfortunately I went back to the original rom.
look closely at the images I shared in a previous post and you will see what I am talking about. i hope this issue will be fixed as the pixel rom is really awesome and well optimized.
