For instance:\r\n- Background\r\n  - Content\r\n    - Header\r\n      - Button\r\nEach node has an associated DIV element displayed as a plain color panel.  I am adding Position component to the Content node, ad start an animation that moves Content alongside the X axis.  I expect that the entire subtree (Content-Header-Button) moves when I move its root node.  The subtree indeed moves, but it does not do it synchronously.  The Header seems to be one frame behind Content, and Button seems to be one frame behind Header, creating a weird wavy effect.  I assume there is a bug somewhere, which does not propagate position changes immediately down the render tree.\r\n\r\nI recorded a short video illustrating the problem:\r\nhttp://manumatix.com/dev/bugs/animation1/famous-animation-lag.mp4\r\n\r\nYou can try it live here:\r\nhttp://manumatix.com/dev/bugs/animation1/live/html/try-device.html\r\n(just click on the button in the top-right corner)\r\n\r\nThe entire code of this example can be downloaded here:\r\nhttp://manumatix.com/dev/bugs/animation1/animation-lag-20150526.zip"},"comment":{"url":"https://api.github.com/repos/Famous/engine/issues/comments/105679189","html_url":"https://github.com/Famous/engine/issues/190#issuecomment-105679189","issue_url":"https://api.github.com/repos/Famous/engine/issues/190","id":105679189,"user":{"login":"42experts","id":12565165,"avatar_url":"https://avatars.githubusercontent.com/u/12565165?v=3","gravatar_id":"","url":"https://api.github.com/users/42experts","html_url":"https://github.com/42experts","followers_url":"https://api.github.com/users/42experts/followers","following_url":"https://api.github.com/users/42experts/following{/other_user}","gists_url":"https://api.github.com/users/42experts/gists{/gist_id}","starred_url":"https://api.github.com/users/42experts/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/42experts/subscriptions","organizations_url":"https://api.github.com/users/42experts/orgs","repos_url":"https://api.github.com/users/42experts/repos","events_url":"https://api.github.com/users/42experts/events{/privacy}","received_events_url":"https://api.github.com/users/42experts/received_events","type":"User","site_admin":false},"created_at":"2015-05-26T21:58:32Z","updated_at":"2015-05-26T21:58:32Z","body":"Much appreciated!"}}
