The solution in that patch was to consider stacking-order changes as "property changes" on layers. However, this is not an ideal clean correct design. The better design is for damage tracker to actually track changes in an order-dependent manner (assuming it turns out to be practical). Indeed, the damage tracker is already assuming order-dependence (expanding damage due to filters assumed the layer list is already sorted in back-to-front drawing order). 873200 1 shawnsingh 2013-04-10 13:33:08 -0700 moved this bug to https://code.google.com/p/chromium/issues/detail?id=230050
