[DevTools Bug]: Excessive CPU Usage
Website or app
Happens even after all tabs are closed
Repro steps
I don't have clear repro steps yet. Occasionally I will notice that Chrome is using 170%-200% CPU. I close all my tabs, and it continues. Then I open the extensions management page and disable react devtools. This immediately fixes the problem. Re-enabling the extension does not re-engage the high cpu issue.
How often does this bug happen?

This is interesting, thanks for reporting. If you are saying that disabling React DevTools immediately fixes the problem, then the issue is somewhere in the service worker, potentially a deadlock.
I would really appreciate if you can provide any reproducing example, or you if you can validate on a small sample of tabs that closing all of them doesn't free CPU, unless React DevTools extension is disabled.
@hoxyq I'll keep an eye on it. I spend most of my day on our app at groovehq.com, but in the local development version. It's possible that something is happening there. Hard to pinpoint, but I'll give it a try!
i had the same issue. it went away when i disabled react tools on all wesites except localhost:4000. it appears that react tools add-on on other websites was causing this issue. it could be concurrency related, or a bug that crashed the tool on non-, react sites.
Just wanted to chime back in here. This is still happening, but I cannot pin it down to a specific set of tabs.
