Description Brent Fulgham 2014-06-10 15:47:29 PDT
Certain markup can cause the Windows tiled drawing logic to waste resources laying out and rendering off-screen rectangle. This can be triggered if a DOM element has a style with a very large negative (e.g., -100,000) 'left' property.

Our Mac code is much smarter about this kind of thing, and excludes rects that are not visible.

We should do the same on Windows.

This has been complete for some time.
