To fixed it I pretty much copied in the whole style sheet and then I changed all the opacities to 1 and set all the filters to 1. That took the hover off of everything, but the circles. To fix that, I changed most of the colors to #000.
I’m pretty sure this will fix it:
.hentry.no-thumbnail {
background: #000;
border-radius: 180px;
overflow: hidden;
transition: background .4s ease-in-out;
-webkit-transition: background .4s ease-in-out;
-moz-transition: background .4s ease-in-out;
-o-transition: background .4s ease-in-out;
word-wrap: break-word;
width: 180px;
max-width: 180px;
height: 180px;
max-height: 180px;
}
