White space between inline-block elements - html

Question

I feel like this question shouldn't exist anymore, but I can't seem to find a solution. So here goes.
ul {
list-style-type: none;
width:150px;
}
ul.nav_sub_menu > li {
width: 100%;
}
ul.nav_sub_menu > li a {
display: inline-block;
width: 100%;
padding: 2.5px 0px 2.5px 5px;
background: #213059;
color: white;
text-decoration: none;
border-bottom: 5px solid #253767;
}
ul.nav_sub_menu > li a:hover {
text-decoration: underline;
background-color: #253767;
}
<div class="nav_sub_menu_wrapper">
<ul class="nav_sub_menu">
<li>
About me</li><li>
Goals</li><li>
Realizations</li><li>
Future plans</li>
</ul>
</div>
This example generates a styles list with display:inline-block anchor tags
You might notice from the start that each list-item is separated by a horizontal white line between them. If not, try zooming the browser in or out (visible at 110% for me).
The white space isn't visible at all zoom levels and it only happens in Chrome, that's why I am at a loss.
How does one begin to troubleshoot this?
FYI, I have found this link to be useful but it didn't help. My chrome version:
Chrome Version 56.0.2924.87 (64-bit)

That is a weird issue. I think it might be something to do with the pixel resolution or density perhaps. However I managed to fix it with the below code.
ul {
list-style-type: none;
width:150px;
}
ul.nav_sub_menu > li {
width: 100%;
}
ul.nav_sub_menu > li a {
display: inline-block;
width: 100%;
padding: 2.5px 0px 2.5px 5px;
background: #213059;
color: white;
text-decoration: none;
border-bottom: 5px solid #253767;
float: left;
}
ul.nav_sub_menu > li a:hover {
text-decoration: underline;
background-color: #253767;
}
All I added was float: left; to the anchor property and it removed the white line between the list items. Try it and see what it does for different zoom levels. Although it does work for 110% zoom for me.
