Unsolved Google Chrome, Microsoft Edge and Opera all using very high CPU when accessing www.windy.com

[zx6dude]

Hi,
First of all my apologies if this is not the appropriate place for this question.
I know this is not a PC support page, but we are having issues when visiting https://www.windy.com with Chromium based browsers, the browser process starts using a lot of CPU resources. Mozilla seems fine and other sites seem fine.

We tried Windows 10, Windows 11 and Windows Server 2019 and we have tried this using several times, always with the same results, Chromium means high CPU usage, Firefox is fine.
We have tried turning on and off hardware acceleration, this makes no difference.

Has anyone seen this, does a solution exist? Is there a setting on Chromium that will address this?

Thanks
ZX
