Visiting https://mystor.github.io/fission-news-1.html with WebRender
enabled in Firefox, causes it to use ~20% CPU.

I have not yet had time to investigate further.

This is caused by the opacity animation on the cursor.

Blocks: wr-perf, wr-mac
Priority: -- → P3

(Not a priority request!)

nika has since removed the animated cursor from the website. Could
you possibly provide us with the CSS that caused this?

This is the css + HTML which caused it (pretty simple)
