Problem with full-width image resolution since upgrading WordPress 4.4

[gdmorrison]

I have a two full width images on my homepage (the sushi plates) that I uploaded at 1920px wide. Since upgrading to WordPress 4.4, scaled down versions of these images are being displayed:

I want to display: /wp-content/uploads/2015/07/sushi-border-top.png
But this is being used: /wp-content/uploads/2015/07/sushi-border-top-1280×57.png

I think this problem is due to WordPress’ new responsive image feature but I would like to force the full resolution image to display as the scaled version is blurred when viewed on high resolution monitors. I have chosen “Full” for the image size in the page builder and this wasn’t a problem before upgrading WordPress.

Hi,

WordPress 4.4 included a there long awaited responsive images feature. https://make.wordpress.org/core/2015/11/10/responsive-images-in-wordpress-4-4/.

You can test this to disable it, please add this to your child theme’s functions.php file:

function sf_disable_srcset( $sources ) {
return false;
}
add_filter( 'wp_calculate_image_srcset', 'sf_disable_srcset' );
