The : at the end of chat names is overlapping with the last character of each name. And it does not do it with BTTV disabled, so I believe this is a BTTV issue.
Can confirm this (i.e. it's not you), and is absolutely BTTV. This appears to be caused by the following CSS at https://cdn.betterttv.net/css/betterttv.css?v=7.0.3
.chat-line .colon, .conversation-chat-line .colon {
margin-left: -3px;
}
Related HTML is <span class="colon">:</span>
Removing the margin-left property, or assigning it to inherit rectifies the issue.
