I got so annoyed by various apps (VScode, Chromium, Firefox, Thunderbird) burning CPU/GPU cycles and and making my laptop hot and sluggish with spinners on otherwise static content, that I made this little page to fight this.

Doing it 30x more frequent than needed costs more, no matter if it's only 1 pixel.
This problem is not isolated to me or to just one machine. Check out the chromium bug about the tab loading spinner, for example. It is a "simple" spinner as well.
Or the Zed editor, which spams screen redraws even when nothing changes at all, so it has high GPU usage for still picture.
