Why does the updated Chrome Timeline behave differently?

Question

Google Chrome

Good evening! In version 37 of Chrome, the Timeline tool, when you click on the "Record" button, immediately displayed fps graphs. And it was very convenient to track the change in fps in different parts of the page.
After Chrome has been updated (perhaps this is due to its update, this is just my guess), by clicking on "Record", Timeline first calculates "events colled", and only then displays my favorite charts. Which I don't find as comfortable as before. After all, I do not see the dynamics of change. Maybe someone knows how to do it the way it was before (without outputting "events colled" first)? Or is it a more convenient feature that needs to be used correctly?
