Shaky text when using transform scale

Question

I am trying to scale the size of a button on hover, but when this is done, the text looks shaky. I looked at some other posts and tried some of the suggestions, such as using -webkit-backface-visibility:hidden;, transform: translateZ(0); and -webkit-transform-style: preserve-3d;, but none seemed to work.

Here is the fiddle: https://jsfiddle.net/ad7n17so/

(I am using Firefox, if that makes a difference)

.button {
  margin-left: 30px;
  background: #FF0000;
  color: #FFFFFF;
  padding: 0.4em;
  width: 100px;
  transition: all 0.3s ease-in-out;
  -moz-transition: all 0.3s ease-in-out;
  -webkit-transition: all 0.3s ease-in-out;
  -o-transition: all 0.3s ease-in-out;
}
.button:hover {
  -ms-transform: scale(1.25); /* IE 9 */
  -webkit-transform: scale(1.25); /* Chrome, Safari, Opera */
  transform: scale(1.25);
}

Answer 1

Just an FYI for people with shaky/jittery images with transform: scale(1.05) on :hover on Firefox, this fixed my problem.

transform: scale(1.05) rotate(0.02deg);

So it's totally a fake rotate Firefox hack that stops this glitchy image scale effect.

backface-visibility: hidden; let the situation better, but the text rendering remains weird (crispy at Firefox, Blurry on Chrome). This problem becomes smaller (mainly on Chrome) removing the padding and using a bigger line-height instead:

.button {
  background: tomato;
  width: 100px;
  -webkit-transition: 0.3s ease-in-out;
  -moz-transition: 0.3s ease-in-out;
  -o-transition: 0.3s ease-in-out;
  transition: 0.3s ease-in-out;
  -webkit-backface-visibility: hidden;
  backface-visibility: hidden;
  text-align: center;
  line-height: 1.8em;  
}

.button:hover {
   -webkit-transform: scale(1.25);
   -moz-transform: scale(1.25);
   -o-transform: scale(1.25);
   -ms-transform: scale(1.25);
   transform: scale(1.25);
}

<div class="button">Test Button</div>
