When doing web development I sometimes hear the fans start making noise and find the Google Chrome process stuck at 100% CPU when checking top
. This kills my battery life.
The internal Process Monitor shows no tab using the CPU, it's the main thread. A weird thing is that even closing all visible windows will not kill the process, so I have to kill it from the command line.
Since this doesn't seem related to one specific page, I would guess it's related to either some internals (in Dev Tools, likely) or some extension. In the latter case I could disable some extensions and see if I could spot a difference. But is there some other way of finding what the hell it is actually doing? Attaching a debugger seems somewhat overkill.
