Dev channel update to 83.0.467.0 is live
For me the CPU spikes happen on random tab (GMail or Google Calendar being most frequent) or extension (sometimes LastPass, sometimes Ghostery). Ending the process will fix the issue for a while but it does happen again (several times an hour).
It looks like it occurs on all extensions. I'm getting it with an adblocker and a colour picker extension.
It's driving me mad as my PC's cooling works with CPU usage, so my fans (10 of them) suddenly go in to a tack off mode.
And I got this with the Video Downloadhelper extension.
So the problem seems to be something to do with extensions, but not just one specific one.
DavidGB (and everybody else seeing high CPU use), we think this actually has something to do with heavy Javascript use in general, since it's also been seen in non-extension processes. It seems to be very random though, meaning that it's hard to get into this state on-demand. If anybody can find a way to reproduce this on demand, it would really help our investigation!
josh_bodner I triggered high CPU usage when I use this extension: https://chrome.google.com/webstore/detail/nordvpn-1-vpn-proxy-exten/fjoaledfpmneenckfbpdfhkmimnjocfa
Not only this but one of the way I can reproduce. I've seen this issue even on new tab page. Sometimes closing one tab page with high CPU usage will get another tab page to become high CPU usage.
