    I know about tools that let me see the paint rectangles, but it's harder to find out *why* they're so big (which DOM manip is triggering it)

        @wycats ran into page wide paints the other day and applying `overflow: hidden` to a parent shrank it. Voodoo. Please re-tweet responses

        @wycats I'm told that it "creates a new layer in the rendering engine". Second hand voodoo.

        @wycats @canuckistani copying you - it's the "show me which element/style caused it" layer/paint tool quandary, the biggest problem to solve

        @wycats I'm just saying that hovering rects shows cause/effect repaints. Recording timeline and hovering paint record shows its dimensions

        @wycats position:absolute & overflow:scroll on the container DIV might trigger page-wide repaints upon scrolling (snap.js for ex. does that)

        @wycats such as what kind of CSS rule for instance. In practice it remains a pretty under documented debugging process.
