could you solve it? i have the same problem
Topic summary
Low-resolution images appear in the Featured Collection on the homepage, affecting both the primary product image and the hover (second) image, despite the originals being high-resolution and displaying sharply on the product page. The poster suspects the issue stems from how the Featured Collection handles media previews.
Multiple users confirm the problem, with one specifying it occurs in Shopify’s Dawn theme. They report the issue started in Dawn version 8.0 and persists through version 13.0.
Shopify support reportedly did not provide a solution, and direct contact with the theme developer is not available. No fixes or workarounds were shared; the issue remains unresolved and open.
