When I deploy my website using Cloudflare, webpages load a bit jerky in the dark theme

I recorded a GIF animation when a web page refreshes, and the white theme web page flashes by before turning into a black theme. My web page is deployed on many platforms, such as Vercel and Netlify, and this situation does not occur. This situation only occurs on Cloudflare. Is there any solution?

The problem has been solved, just turn off Cloudflare Rocket Loader
