Details

At this stage of brainstorming, bug 1219145 will over-approximate animation-jank-critical to "is the vsync timer on". In particular, this means that we consider even OMT animations as jank-critical, although main thread activity will actually not impact framerate.

We can most likely refine this by requesting the information rather from:
- animation manager;
- transition manager;
- SVG animation manager;
- requestAnimationFrame manager;
- animated images manager;
- ... more?
about:performance is being redesigned; mass closing the bugs related to parts of the current about:performance page that we are not keeping.

Our goals with the redesign are to reduce the overhead caused by having the page opened, increase the reliability of the displayed information, and make the offered information actionable for most users. The back-end work is being tracked in bug 1419681.
