Performance

Describe the bug

the banner on the grant sub-page of processingfoundation.org makes the website take up 100% of the CPU.

Image

my quick performance test from the firefox devTools revealed, that there are a lot of calls to requestAnimationFrame callback which sometimes take up to 500ms and therefore blocking the main thread.

Image

I originally noticed this when I had my own p5.js sketch running on a second screen and the sketch suddenly lagging extremly behind. I"ve also conducted a quick test on my machine with chrome where the problem doesn't seem to appear, tomorrow I might also test it on my macBook with safari.

Expected behavior

The processingfoundation.org/grants banner-sketch shouldnt be taking up 100% of browser CPU
