Fading look on my featured images

In your Child Theme or CSS Editor Plugin try this code:

.post-thumbnail::after {
    background-image: none;
}

*Note
If your theme has a custom CSS Editor in it, you can also paste the code in there.

Never edit core CSS or PHP files under Appearance > Editor. Your edits will be deleted when the theme is updated.
