CSS for rounding the avatar flair seems missing.

In the meantime a fix appears, you can try to add this in your theme CSS:

.latest-topic-list-item .topic-poster .avatar-flair {
    bottom: -2px;
    right: 6px;
    
    display: flex;
    align-items: center;
    justify-content: center;
    
    background-size: 18px 18px;
    background-repeat: no-repeat;
    background-position: center;
    
    border-radius: 12px;
    width: 24px;
    height: 24px;
}
