Has anyone else noticed the 'Performance' graphs in the Impact Debug mode is very...unstable as of the 31.0.1650.63 Chrome update?

A picture says a thousand words... Please note nothing in these projects have been changed. It is running the 'blank' Impact game when you first buy the software

Here is the 'blank' "It Works!" project in Chrome 31.0.1650.63: (Latest stable Chrome)

The FPS is very erratic, changing anywhere from 45 - 64 fps...multiple times a second

Here is the exact same project with the exact same Impact version, but running on Chrome 31.0.1650.57:

The FPS stays a stable 60fps. No erratic spikes anywhere.

I had a friend check his Impact project in the latest Chrome, and this is what he was seeing with Chrome stable 31.0.1650.63

Anyone else experiencing the same thing? Any ideas as to what might be the cause?
