If the "default" state of an x-show on page load is "false", you may want to use x-cloak on the page to avoid "page flicker" (The effect that happens when the browser renders your content before Alpine is finished initializing and hiding it.) You can learn more about x-cloak in its documentation.
@vincent15000 no worries; it's caught everyone at some point! The docs show an interesting workaround using a template element and without x-cloak - if you want to give that a try instead!
