css - Chrome Font appears Blurry

Question

It's doing my eyes in!

looks fine in IE and Firefox

Chrome(Above)

Running version 39 of chrome, only appears blurry in a modal box, does not make any difference if I change the font family.

This is the CSS (for label "Start") the browser renders the following

box-sizing: border-box;
color: rgb(85, 85, 85);
cursor: default;
display: block;
float: left;
font-family: sans-serif;
font-size: 12px;
font-weight: 600;
height: 24px;
line-height: 17.142858505249px;
margin-bottom: 0px;
margin-top: 0px;
min-height: 1px;
padding-left: 15px;
padding-right: 15px;
padding-top: 7px;
position: relative;
text-align: right;
visibility: visible;
width: 89.65625px;

Is it the browser or CSS?

--UPDATE---

Ok looks like its this CSS

.md-modal {
    position: fixed;
    top: 50%;
    left: 50%;
    width: 50%;
    max-width: 630px;
    min-width: 320px;
    height: auto !important;
    z-index: 2000;
    visibility: hidden;
    -webkit-backface-visibility: hidden;
    -moz-backface-visibility: hidden;
    backface-visibility: hidden;
    -webkit-transform: translateX(-50%) translateY(-50%); <--- This line
    -moz-transform: translateX(-50%) translateY(-50%);
    -ms-transform: translateX(-50%) translateY(-50%);
    transform: translateX(-50%) translateY(-50%);
}

However if I take it out my modal no longer centres?

Answer 1

I fixed this issue by subtracting 0.5px from the value of the Y-axis. So instead of doing:

transform: translateX(-50%) translateY(-50%);

I did this:

transform: translateX(-50%) translateY(calc(-50% - .5px));

This solved it for me and I find this a cleaner solution then fiddling around with the percentage or using Javascript.
