We are spending 10% of the time in nsIFrame::GetOffsetToCrossDoc() and overall it seems like we're doing more than we should be.
What's the stack to that? Invalidation, or something else?
nsDisplayList::ComputeVisibilty called by nsLayoutUtils::PaintFrame()
There is an existing bug for scrolling on gmail being slow as a regression from retained layers, that's bug 579260. Jeff, would you be willing to reprofile if I gave you a patch to try?

Created attachment 461315 [details] [diff] [review] patch to try This undo's some changes that were made in bug 563878. I'm interested in how this affects the GetOffsetToCrossDoc time.
I believe the problem in gmail scrolling is that we're painting much too much, not that any one function is slow.
