I have this problem as well. Indeed I am using twentythirteen.

I noticed that the image is always exactly 20px bigger than the colored box.

So I checked the code and found something odd in post-tiles.php
On line 403 and 410, I found these lines of code:

$posttiles_width = $posttiles_li_width - 20;
$posttiles_height = $posttiles_li_height - 20;

It’s fixed when I removed the -20 on both lines. Why -20 ?

I created a Child theme the normal way. That plugin you mentioned is not working, I guess.

I also copied the meta-box folder. But I still can’t change anything using style.css.

I love the gamepress theme. But I hate that I can’t create a child theme.
