Chrome CSS错误:旋转元素中的"translate3d"不遵循"overflow:hidden"

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;
}

      </div>

  </div>
</div>

我有一个带有透视的旋转元素,在其中我有一个'滚动'div,它是垂直变换的(想象一下杂志翻页体验,每页内有滚动的div).我添加will-change: transform到内部div,打破了外部容器overflow: hidden.这似乎是Chrome合成器的一个错误.

有谁知道任何变通方法？我想保留该will-change属性,因为它可以显着提高移动Chrome上的动画效果.

编辑:看起来这不是特定于will-change属性,而是任何使内部div成为自己的合成层的属性.当我删除will-change属性但将转换更改为translate3d类似地提高性能并显示错误.内部div上允许旋转父级正确渲染的唯一类overflow: hidden是添加2D变换的类.

尝试像这样的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;
}

你可以玩弄perspective()和transform-origin价值观。
