Hello,
1) In general, our theme is already optimized and don’t have too many resources to make your website slow. Most likely, your website performance suffers from the content you have added to your website. It may happen in case of too many plugins, large not optimized images or other resources. So we suggest you remove unnecessary plugins, install some kind of JS & CSS optimizing plugins like Better WordPress Minify and a caching plugin like WP Super Cache. Also, you can use GTmetrix tool to see what makes your website slow and optimize these parts of your website.
2) Try to add the following code snippet to the Custom CSS area in Theme Settings to fix this issue.
.product-grid-item .product-image-link img,
.product-grid-item .hover-img img {
width: 100%;
object-position: 50% 50%;
object-fit: contain;
font-family: 'object-fit: cover;';
height: 175px;
}
Also in the last update, we added an option to install all product titles in one or two lines. You can find the option here Theme Settings -> Shop -> Product styles -> Product title lines limit http://prntscr.com/m4gysz
Kind Regards
