Remove wpautop from shortcode content / remove whitespace in buffering

You do not need a plugin to do this. Just add 3 lines of code to the end of the functions.php file in your active theme:

remove_filter( 'the_content', 'wpautop' );
add_filter( 'the_content', 'wpautop' , 99 );
add_filter( 'the_content', 'shortcode_unautop', 100 );
