Comment (by bobbingwide):

 I've recently noticed this where my hosting ( TSOhost ) have switched to
 PHP 7.3 and have set `zlib.output_compression=on` by default, and where my
 sites have WP_DEBUG true.

 Is it not possible to detect the PHP ini setting and not attach the
 `wp_ob_end_flush_all` filter function to `shutdown` when it's set?
