CSS 1px 边框笔划在边框半径周围中断

这是针对网络开发人员的.当在圆形或具有真正圆角的正方形上使用 1px 边框半径时，笔划开始中断.如果我们将其更改为 2px，它会变得越来越好，我们添加的 px 越多.但是有没有办法用 1px 的笔画来解决这个问题?

This is for web dev. When using a 1px border radius on a circle or a square with really rounded corners, the stroke starts to break. If we were to change it to 2px's it would get better and better the more px we add. But is there a way to fix this problem with a 1px stroke?

background: rgba(32, 32, 32, .9);
height: 30px;
width: 30px;
border: 1px solid white;
border-radius: 20px;
:hover {
 height: 300px;
 width: 200px;
}
