I can see the truncated letter widths in NetSurf r12793. An extracted 
copy of what/gif however does display correctly in NetSurf. The 
problem may be related to scaling. Below is some minimal source, try 
it at different NetSurf window widths.

<style type = "text/css">
   .what {
       text-align: center;
       background-color: white;
       width: 40%;
       margin-left: 0px
       margin-top: -20px;
       margin-bottom: 20px;
       border: medium solid #406948;
       border-radius: 40px;

    }
