Recently without enabling able to see first meaning full paint value in video compare timing graph can any one explain what it exactly refers?
That's actually a Chrome metric, not a Lighthouse one (Lighthouse just reports it like WebPageTest does). Here's a reasonably short explanation of it: https://github.com/tdresser/time-to-firs...gful-paint
