css - Why is text getting blurry and wobbles during 2d scale transform

I want to make this card to scale on hover (including the elements inside it) but the text wobbles/jitters during the transformation (when you hover the card) and gets blurry during and after it's scaled (sometimes, with some ratios more than others, which I think is due to sub-pixel value rounding).

How do you remove that wobbling and blurriness during the transformation?

  • I don't care about IE browsers, I only want it to work in the latest Chrome.

  • It seems that it's caused by the transition property.

Codepen #1: https://codepen.io/x84733/pen/yEpYxX

.scalable {
  transition: 0.3s ease-in-out;
  box-shadow: 0 6px 10px rgba(0,0,0,0.14);
}
.scalable:hover {
  transform: scale(1.05);
  box-shadow: 0 8px 40px rgba(0,0,0,0.25);  
}

.card {
  width: 100%;
  background: white;
  padding: 20px;
}

body {
  width: 50%; 
  height: 100%; 
  background: #999;
  padding: 20px;
}
<div class="card scalable">
  <div>here's some description</div>
</div>

Instead of using scale you can consider a translateZ with a perspective. Make sure to define the perspective initially to avoid the bad effect when moving the cursor fast:

.scalable{
  transition: 0.3s ease-in-out;
  box-shadow: 0 6px 10px rgba(0,0,0,0.14);
  transform:perspective(100px);
}

.scalable:hover {
  transform:perspective(100px) translateZ(5px);
  box-shadow: 0 8px 40px rgba(0,0,0,0.25);  
}

.card {
  width: 100%;
  background: white;
  padding: 20px;
}

body {
  width: 50%; 
  height: 100%; 
  background: #999;
  padding: 20px;
}
<div class="card scalable">
  <div>here's some description</div>
</div>
