Description Jon Lee 2022-02-09 12:01:07 PST 
Scroll down until you see "Each frame is on screen for approximately 0.04 seconds". The frame count at the bottom lags and is super slow compared to Chrome.

Scroll further until you see "From storyboard to final frame, each film takes an average of three to five years to create what you see on screen.". There is a blip after the wipe.

This page has many, large elements with blur(0), which triggers creation of software buffers and does software rendering which could be avoided.

We should optimize away no-op filter chains.
Comment 4 Simon Fraser (smfr) 2022-03-03 20:48:09 PST 
...except that would be observable if the filter contents contain non-sRGB content: https://codepen.io/smfr/pen/PoOVmPX
