No effect with WP 4.5.2

Should it still work with WP 4.5.2.?
I noticed that the images I upload are saved as is. No reduction in size, no matter what compression level I set.

In case you want to update your plugin. This is how I do it (note: this code produces sometimes some text output which it of course should not…):

function filter_wp_handle_upload($array, $var)
{
    $name  = $array["file"];
    $image = wp_get_image_editor($name);
    if (!is_wp_error($image)) {
        $temp = $image->generate_filename();
        $image->set_quality(75);
        $saved = $image->save($temp);
        if (file_exists($temp)) {
            if (filesize($temp) < filesize($name)) {
                rename($temp, $name);
            }
    	} else {
     	   unlink($temp);
    	}
	}
    return $array;
}
;

// add the filter
add_filter('wp_handle_upload', 'filter_wp_handle_upload', 10, 2);
