Hi Ryan,
I've tried to replicate this locally, seems it will truncate the tittle by default. However, you can try to manually truncate the tittle by edit the file or override the file:
[example using the default showcase layout]
JOOMLA_FOLDER\modules\mod_easyblogshowcase\tmpl\default.php
change the code:
<a href="<?php echo $post->getPermalink();?>"><?php echo $post->title;?></a>
to:
<a href="<?php echo $post->getPermalink();?>"><?php echo substr($post->title,0,20).'...'?></a>
Change the no(20) to your preferably character length.
