 * Hi,
 * As title states, my site gets an issue where some text are shown on page before“
   loader” has started loading.
 * I’ve located the issue to the cache, as when purged the issue stops but returns
   again after some time. I’ve made a recording of the issue: [https://youtu.be/rG0O79_pHA](https://youtu.be/rG0O79_pHA)
 * My question is; how do I prevent this issue from arising again?

 * Hi,
 * Video is not available. Most likely it is related to Critical CSS. When Generate
   Critical CSS in enabled, it can result in FUOC (Flash of unstyled content) as
   the browser is still loading the css, once the css is loaded the browser refreshes
   to apply the css. It looks a bit “flashy”. You can avoid that, but then you need
   to add some custom CSS rules in Extra Critical CSS. Fastest solution: disable
   Generate Critical CSS
