Open the new google IO site for 2015: https://events.google.com/io2015/ Click on the "Learn more about I/O" to go to: https://events.google.com/io2015/about Observe animation jank. Here is a profile where did this a couple times: http://people.mozilla.org/~bgirard/cleopatra/#report=ff1340155897196d126bbfaf89288b804a89c43e Putting this in gfx because the profile shows some massive rasterize blocks. Note, the large script blocks are probably where they are doing their "FLIP" technique described here: http://aerotwist.com/blog/flip-your-animations/
Any thoughts on the profile in comment 0?
Multiple long (60ms+) instances where we are stuck on NtGdiDdDDILock in the windows gfx libs. Maybe this is more a question for Bas. I'm on windows 8.1.

We're spending a noticeable amount of time in RenderLayerWithReadback. That doesn't seem good.
Is this still happening and/or do we still care?
