I’m surprised that this technique works to test repainting behavior, since DumpRenderTree is supposed to invalidate everything by default. Anyway, even if it works, it appears to take a full second. You should use the standard mechanism for repaint tests instead (see LayoutTests/fast/repaint/resources/repaint.js).
