Chrome :旋转元素中的"translate3d“不服从”溢出:隐藏“

Question

看看这个CodePen，看看我的意思：

​

.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;
}

<h1>Incorrect (uses will-change):</h1>

      <div class="scroller will-change">

我有一个具有透视图应用的旋转元素，其中我有一个“滚动”div，它是垂直转换的(想象一下在每个页面中滚动div的杂志翻页体验)。我将will-change: transform添加到内部div中，这破坏了外部容器overflow: hidden。这似乎是Chrome排字器的一个缺陷。

有人知道什么解决办法吗？我想保留will-change属性，因为它大大加快了移动Chrome上的动画速度。

编辑：它看起来并不是特定于will-change属性，而是任何使内部div成为它自己的复合层的属性。当我移除will-change属性但将转换更改为translate3d时，它同样提高了性能并显示了错误。内部div上唯一允许旋转的父类正确呈现overflow: hidden的类是添加2D转换的类。

试试像这样的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。
