Description Simon Fraser (smfr) 2008-12-18 09:39:34 PST 
Bug 22570 fixed issues with cached clip rects and reflection painting by computing the clip rects on the fly when painting reflections (which has to be done because there's a temporary shift in the rootLayer).

However, while painting that reflected content, each layer is going to recompute its clip rects all the way from the root, which is O(n^2).
