I'm studying Analyze runtime performance using the demo https://googlechrome.github.io/devtools-samples/jank/
When I open FPS meter (using Frame Rendering Stats in Rendering tab), it shows 10.8 fps:
However, when I record using Performance, there are lots of red blocks and a few green blocks. Every 20 red blocks, one green block. But in every block it shows 60 fps, which is totally wrong
As the red blocks are dropped, and I have noticed that during the 20 red blocks, the animation has never change. So I just imagine maybe the real value is 60 / 20 = 3 fps. This is reasonable as actually there are only 3 green blocks inside 1000ms. But that is still not equal to 10.8 fps. It really make me confused!
Supplement: In the document it shows 12 fps(see the image here), but it doesn't show any red dropped frames. Maybe it is due to the dropped frames are brought in 2020(https://docs.google.com/document/d/1-KP3fAjemdm7lnvCll9T1Lg-ikCzRPI-oNCp8fHAQCc/edit#heading=h.neguedjcao67), and the document is actually outdated?
