It seems that in the recent releases of WordPress, changes were made to the mime type handling to make sure that files have the extension they say they do: https://make.wordpress.org/core/2018/12/13/backwards-compatibility-breaks-in-5-0-1/ This poses an issue for SVG files without the tag in them. SVG is actually an XML, and WordPress is now requiring to have a … Read more
add_action(‘add_attachment’, ‘create_post’); function create_post( $attach_ID ) { $attachment = get_post( $attach_ID ); $my_post_data = array( ‘post_title’ => $attachment->post_title, ‘post_type’ => ‘post’, ‘post_category’ => array(‘0’), ‘post_status’ => ‘publish’ ); $post_id = wp_insert_post( $my_post_data ); // attach media to post wp_update_post( array( ‘ID’ => $attach_ID, ‘post_parent’ => $post_id, ) ); set_post_thumbnail( $post_id, $attach_ID ); return $attach_ID; }
In recent versions of WordPress (5.0.1 or higher) file upload security has been tightened by actually checking the content of an uploaded file using the PHP function finfo_file() to determine if the file extension matches the MIME type. This has proven problematic since files with the same file type and extension may yield different MIME … Read more

You are probably missing ImageMagick (PHP extension). Install it and the JPG artifacts will be gone.
I guess what you’re looking for is the $content_width global that would basically limit the width of your images, used in functions.php. Some more info here: http://mainstreetopen.com/wordpress-26-and-full-width-images/

This is untested, but I think you can just define wp_handle_upload_error in your functions.php file and return custom error messages. If you look at where that function is defined in that file, if ( ! function_exists( ‘wp_handle_upload_error’ ) ) { function wp_handle_upload_error( &$file, $message ) { return array( ‘error’=>$message ); } } You can see … Read more
The relative path, including the date directories, is stored in the postmeta for the attachment’s post, using the _wp_attached_file meta_key. If you examine the data for that key, you’ll find that the meta_value is 2012/08/example.jpg or something similar to that. This is used to build the URL.
Testing the plugin provided in this Answer, I just saw that media_handle_sideload generates exactly this pattern, jpeg extension as well (instead of jpg). Following its path through the core, it seems that only the filter wp_handle_upload could be used for dealing with that.
