Scrolling performance on is horrible on http://graphics

This is one example where switching to Skia makes things worse. Marcus, I see you on the bug already, did this get better with the work you recently did on OS X? In other words, was it even worse?

The work I did on OS X hasn't landed yet (bug 1123019), but it does make scrolling on this page a lot better!
Depends on: 1123019
And it's probably the first patch in bug 1123019 that makes the difference, and since that touches shared code in DrawTargetTiled.cpp, it will probably also help Skia.
Confirming that turning off tiling does improve the performance, so it makes sense that bug 1123019 would make a difference.
This works for me now, Doug, are you still seeing the problem?
