Woocommerce product image with poor quality in Chrome

Hi,

Im using woocommerce with enfold theme, and In some of my products the main image appears with very poor Quality.
I already fix sizes and regenerate all thumbnails multiple times, the problem only appear on Chrome, in other browsers like safari everything its ok.
The problem Its only at the main product image, the catalogue images and miniatures are fine.
Can your please advise?

Thanks,

Frederico
