html - Weird CSS3 Transition (flickering)

Question

When I hover unto my button, it gives a white flash first when starting the transition. Why does it sort of flickers when I apply a css3 transition to my button? My browser is Google Chrome

See here

<button>Log In</button>?

CSS:

button {
    background: #ff3019;
    background: -moz-linear-gradient(top,  #ff3019 0%, #cf0404 100%);
    background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#ff3019), color-stop(100%,#cf0404));
    background: -webkit-linear-gradient(top,  #ff3019 0%,#cf0404 100%);
    background: -o-linear-gradient(top,  #ff3019 0%,#cf0404 100%);
    background: -ms-linear-gradient(top,  #ff3019 0%,#cf0404 100%);
    background: linear-gradient(top,  #ff3019 0%,#cf0404 100%);
    filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#ff3019', endColorstr='#cf0404',GradientType=0 );
    border:1px solid #890000;
    display:block;
    margin:0 auto;
    width:200px;
    padding:5px 0;
    border-radius:8px;
    color:#fff;
    font-weight:700;
    text-shadow:0 1px 1px #000+50;
    box-shadow:0 2px 3px #000+150;
    -webkit-transition:background linear .5s;
}
button:hover {
    background:#ff3019;
}
button:active {
    background:#cf0404;
}

?

I got rid of the flickering. Add ?-webkit-backface-visibility: hidden;? to the elements you are transitioning. Voilà!
