Were you using Canary? There have been improvements to Task Manager to make it easier to use that just recently came to the Mac.

I was on canary on Mac. I think it was up to date.

The Mac's task manager should behave identically to the Views task manager. If there is any difference, assign to me. If not, then your issues are with the core TM code, and Nick is your peep.

Yes, this is an area we have plans to improve for --top-document-isolation mode, which is what this bug is about.  (Things are already in decent shape for --isolate-extensions and full --site-per-process.)

Specifically, the http://web-subframes.invalid/ URL is just a short-term placeholder.  I think Nick has some plans for how to improve how the TDI process is displayed.

Ojan, what do you think? This is https://codereview.chromium.org/2437253002 .

lgtm, thanks! What does it look like if there are frames from multiple tabs in a single process?

This doesn't have the automagic sorting (it's manually sorted by task name) but like this.

So the Task Manager naming issue is fixed. Does this bug include other issues that need fixing?

I consider this fixed.

Ojan?

Agreed. Thanks!
