Deprecate scroll update latency histograms |
|||||||
Issue descriptionOld Event.Latancy.. scrolUpdate metrics report the latency only for touch scrolls. They use the average event time of start and end components. Deprecate them with new latency metrics that report latency for both wheel and touch scrolls. The new metrics are calculated based on the difference between the first and last event time of the start and end components, respectively.
