Jeff mentioned in today's daily that he and Matt we profiling display list building, and saw things related to APZ (specifically, APZ-specific codepaths in ScrollFrameHelper::BuildDisplayList(), and building of event-regions display items) taking a significant portion of time. I'm filing this bug to track this issue. We should investigate the profiles, see what mitigations (if any) we can employ, and be mindful of the performance impact when making further changes to this code. Jeff/Matt, if you could share some profiles, that would be great!
