Figured it out!
The WooCommerce default Product image crop is too small. Just change the crop size to 234×234 for “Catalog Images” and 419×419 for “Single Product Image.”
That should do it!
I have this same problem. I love this theme, but this issue may cause me to look elsewhere. I need the home page to look as good a possible and having blurry pixelated product images doesn’t help.
Any assistance would be greatly appreciated.
