Hey Kris

Took a look at this and at least on Mac not seeing anything particularly out of the ordinary while the page has loaded with no changes, some style changes coming from a setInterval but still idle 97% of the time

Could you do a profile from when you see the issue? Thanks

This looks and smells like a graphics issue, though I can't quickly tell from the profile what's going wrong - perhaps people more familiar with our graphics stack can look a little bit closer.

The priority flag is not set for this bug.
:jbonisteel, could you have a look please?

For more information, please visit auto_nag documentation.

I can't reproduce but I suspect an ad was causing stuff to invalidate. The GPU times on this page are not too bad (as long as we don't over-invalidate), so I'm putting this under the picture-caching umbrella in the hope that we can better catch these cases where nothing visually change and avoid rendering.

This page seems to run well now.
