Open the new google IO site for 2015:

Click on the "Learn more about I/O" to go to:

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:

Multiple long (60ms+) instances where we are stuck on NtGdiDdDDILock in the windows gfx libs.  Maybe this is more a question for Bas.

We're spending a noticeable amount of time in RenderLayerWithReadback. That doesn't seem good.

[Bas Schouten (:bas.schouten)]

Is this still happening and/or do we still care?
