[DevTools Bug]: Excessive CPU Usage about react

[hoxyq]

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.
