Internet Explorer 11 wobbly CSS3 animation

Please refer to this fiddle: http://jsfiddle.net/eQegA/3/

<div class="spinner"></div>

.spinner {
    width: 100px;
    height: 100px;
    border: 50px solid blue;
    /*border-top-color: #fff;
    border-bottom-color: #fff;*/ /* commented out to see the wobble better */
    border-radius: 200px;    

    -webkit-animation: application-loading-rotate 1s;
    animation: application-loading-rotate 1s;
    -webkit-animation-iteration-count: infinite;
    animation-iteration-count: infinite;
    -webkit-animation-timing-function: linear;
    animation-timing-function: linear;
}

@-webkit-keyframes application-loading-rotate {
  from {
    -webkit-transform: rotate(0deg);
  }
  to {
    -webkit-transform: rotate(360deg);
  }
}
@keyframes application-loading-rotate {
  from {
    transform: rotate(0deg);
  }
  to {
    transform: rotate(360deg);
  }
}

In Google Chrome the rotation is stable, however for some reason in IE11 there is a noticable "wobble" of the circle as it rotates.

Any ideas why it wobbles so? Is there any way to fix it in IE11?

For what it's worth, it also occurs on other browsers. It has to do, how the border is drawn, it's not a perfect round. As far as I know, there isn't a quick fix for this. However you can draw the border as a background image.

.spinner {
display:block;
    width: 200px;
    height: 200px;
    border-radius: 100%;
    background-image:url(http://www.clipartbest.com/cliparts/9iR/RyK/9iRRyKLie.png);
    background-size:100%;

    -webkit-animation: application-loading-rotate 1s;
    animation: application-loading-rotate 1s;
    -webkit-animation-iteration-count: infinite;
    animation-iteration-count: infinite;
    -webkit-animation-timing-function: linear;
    animation-timing-function: linear;
}

@-webkit-keyframes application-loading-rotate {
  from {
    -webkit-transform: rotate(0deg);
  }
  to {
    -webkit-transform: rotate(360deg);
  }
}
@keyframes application-loading-rotate {
  from {
    transform: rotate(0deg);
  }
  to {
    transform: rotate(360deg);
  }
}
