   Mobile timeline scrolling jitter

   I’m in a reduced quality network environment with mobile and learned a bit about the mobile timeline scrolling jitter issue.

   There seem to be a minimum of 3 variables at work:

   • Quality of service
   • Post height dynamic updates as details are fetched
   • Touch event affects scroll position

   It is the third item that might have the most impact

   A simple test is to compare the results when starting a touch scroll gesture at the same Y coordinate on the display vs starting at random Y coordinates.

   I have found that by controlling the touch scroll gesture Y coordinate greatly reduces timeline jitter. Poor QoS makes the problem easy to reproduce

   On the post height rendering issue, perhaps it could be slightly improved by not rendering post height updates while a scroll event is active.
