Bug Description
This is somewhat similar to https:/
After a few cycles of suspend, working with external monitor, running Chrome with 10+ opened tabs causes gnome-shell and chrome to use 60% of CPU just idling. When I do some more active work - it consumes even more. My laptop is hot all the time.

I think this is probably expected for now.
Chrome using significant CPU when tabs are open on non-trivial pages is expected.
And Gnome Shell using noticeable CPU when any window is updating is a known issue, but really a whole class of bugs. For a list of known causes (subject to change), see https:/ /trello. com/c/pe5mRmx7
