The CPU usage is constantly high at 70% when my simple Trello board is at foreground. It drops to almost zero after I switch to another Chrome tab.
Chrome dev console shows a list of errors:
I guess there is a wild timer that keeps running at foreground which consumes a lot of CPU.
Edit1: I have upgraded Chrome to 90.0.4430.93. The issue is still there.
Hi @Bo Hu ,
please share your screenshot to Trello support team as well

if you don't use the chrome extensions and you can reproduce in private mode of browser.
it's bug
It's caused by a Chrome extension "Selection Highlighter". I have to turn it off as adding "trello.com" to its domain blacklist doesn't work. It must have injected some scripts that break trello.

The same issue occurred again today after I disabled the extension. I have no idea what is the root cause and I'm afraid I don't have more time to investigate into it.
I switched to Safari.

agree, just trello board opened is causing increase of the CPU usage couple of times, just let it opened and listen to the fans in your laptop
