In situations where the element has a stacking context for another reason (-webkit-transform, for example), there will already be a stacking context on the element. Consequently, a change to -webkit-overflow-scrolling will have no effect on the existence of a stacking context. In these cases, we see a visible flicker when the (unnecessary) layout is performed. Perhaps a check to see if a layout is required based on the consequent creation/destruction of a stacking context would be more appropriate. 1016124 1 simon.fraser 2014-06-17 09:07:54 -0700 (In reply to comment #0) > In these cases, we see a visible flicker when the (unnecessary) layout is performed. A layout which results in the same rendering should not cause a flicker. What OS are you reporting this flicker on?
