Chrome CSS 错误："translate3d" 在旋转元素内不服从 "overflow: hidden"

Question

看看这个CodePen明白我的意思：

.perspective-container {
  margin: 50px 0;
  perspective: 1000px;
  perspective-origin: 0 50%;
}
.card {
  border: 10px solid blue;
  width: 300px;
  height: 300px;
  overflow: hidden;
  transform: rotateY(-45deg);
}
.card-inner {
  width: 300px;
  height: 300px;
  overflow: hidden;
}
.scroller {
  transform: translate(0, -100px);
}
.scroller-3d {
  transform: translate3d(0, -100px, 0);
}
.will-change {
  will-change: transform;
}

我有一个应用了透视的旋转元素，其中我有一个垂直变换的 'scrolling' div（想象一下滚动 divs 的杂志翻页体验每页内）。我将 will-change: transform 添加到内部 div 并且破坏了外部容器 overflow: hidden。这似乎是 Chrome 合成器的错误。

有人知道任何解决方法吗？我想保留 will-change 属性，因为它可以显着加快移动设备上的动画速度 Chrome。

编辑： 看起来这不是特定于 will-change 属性而是任何属性使得内部 div它自己的合成层。当我删除 will-change 属性但将转换更改为 translate3d 时，同样可以提高性能并显示错误。内部 div 上唯一允许旋转父对象正确呈现 overflow: hidden 的 class 是添加 2D 变换的对象。

试试这个 CodePen:

.container {
  margin: 75px 0;
}

.card {
  border: 10px solid blue;
  width: 300px;
  height: 300px;
  overflow: hidden;
  -webkit-transform: perspective(1000px) rotateY(-45deg);
  transform: perspective(1000px) rotateY(-45deg);
  -webkit-transform-origin: 0 50%;
  transform-origin: 0 50%;
}

.scroller {
  -webkit-transform: translate(0, -100px);
  transform: translate(0, -100px);
}

.scroller-3d {
  -webkit-transform: translate3d(0, -100px, 0);
  transform: translate3d(0, -100px, 0);
}

.will-change {
  will-change: transform;
}

您可以使用 perspective() 和 transform-origin 值。
