CSS Transition Jumpy / Jerky

I have been using the scale() property, which was working fine until a few weeks ago. After the browsers got updated, now I see a jerky/jumpy animation, can someone please point out where exactly my problem is?

Please take a look at the following jsFiddle; in the rollover, the ICON (which is showing "A") will slide in from the bottom and scale at the same time, but it goes down to the starting point creating a jerky/jumpy animation effect.

.ca-menu {
    padding:0;
    margin:20px auto;
    width: 1020px;
}
.ca-menu li {
    width: 200px;
    height: 300px;
    overflow: hidden;
    position: relative;
    float:left;
    background: #fff;
    -webkit-box-shadow: 1px 1px 2px rgba(0, 0, 0, 0.2);
    -moz-box-shadow: 1px 1px 2px rgba(0, 0, 0, 0.2);
    box-shadow: 1px 1px 2px rgba(0, 0, 0, 0.2);
    margin-right: 4px;
    -webkit-transition: all 300ms linear;
    -moz-transition: all 300ms linear;
    -o-transition: all 300ms linear;
    -ms-transition: all 300ms linear;
    transition: all 300ms linear;
}
.ca-menu li:last-child {
    margin-right: 0px;
}
.ca-menu li a {
    text-align: left;
    width: 100%;
    height: 100%;
    display: block;
    color: #333;
    position: relative;
}
.ca-icon {
    font-family:'WebSymbolsRegular', cursive;
    font-size: 60px;
    color: #333;
    text-shadow: 0px 0px 1px #333;
    line-height: 150px;
    position: absolute;
    width: 100%;
    height: 50%;
    left: 0px;
    top: 0px;
    text-align: center;
    -webkit-transition: all 400ms linear;
    -moz-transition: all 400ms linear;
    -o-transition: all 400ms linear;
    -ms-transition: all 400ms linear;
    transition: all 400ms linear;
}
.ca-content {
    position: absolute;
    left: 0px;
    width: 100%;
    height: 50%;
    top: 50%;

    -ms-transition: all 200ms linear;
    transition: all 200ms linear;
}
.ca-sub {
    text-align:center;
    font-size: 14px;
    color: #666;
    line-height: 40px;
    opacity: 0.8;
    position: absolute;
    bottom: 0;
    width: 100%;

remove all the transition property from .ca-icon

Fiddle

also you need only -moz- and -webkit- prefix for @keyframes, the -ms- prefix for @keyframes doesn't exist, it is considered a good practice to include a unprefixed @keyrames also. Although this is not causing the problem, just told you about it.

The problem here is using transition and animation at the same time on .ca-icon.
