This would provide the browser with more hints to avoid re-raster on every frame.\r\n\r\nThe bug occurs in the drawRipple method https://code.google.com/p/chromium/codesearch#chromium/src/third_party/catapult/third_party/polymer/components/paper-ripple/paper-ripple.html&l=190\r\n\r\nIt can be reproduced by paper-button/demo.html, which is run by telemetry bots as per https://code.google.com/p/chromium/issues/detail?id=563504#c16\r\n\r\nSee more details here: https://code.google.com/p/chromium/issues/detail?id=563504#c18\n\n_Copied from original issue: Polymer/polymer#3219_"},"comment":{"url":"https://api.github.com/repos/PolymerElements/paper-ripple/issues/comments/179543732","html_url":"https://github.com/PolymerElements/paper-ripple/issues/67#issuecomment-179543732","issue_url":"https://api.github.com/repos/PolymerElements/paper-ripple/issues/67","id":179543732,"user":{"login":"zmoshansky","id":3180807,"avatar_url":"https://avatars.githubusercontent.com/u/3180807?v=3","gravatar_id":"","url":"https://api.github.com/users/zmoshansky","html_url":"https://github.com/zmoshansky","followers_url":"https://api.github.com/users/zmoshansky/followers","following_url":"https://api.github.com/users/zmoshansky/following{/other_user}","gists_url":"https://api.github.com/users/zmoshansky/gists{/gist_id}","starred_url":"https://api.github.com/users/zmoshansky/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/zmoshansky/subscriptions","organizations_url":"https://api.github.com/users/zmoshansky/orgs","repos_url":"https://api.github.com/users/zmoshansky/repos","events_url":"https://api.github.com/users/zmoshansky/events{/privacy}","received_events_url":"https://api.github.com/users/zmoshansky/received_events","type":"User","site_admin":false},"created_at":"2016-02-04T00:07:43Z","updated_at":"2016-02-04T00:07:43Z","body":"Also note previous discussion https://github.com/Polymer/paper-ripple/issues/10. Looks great on desktop, although on Android (Zenfone2) the ripple is very janky. Needs much more butter. \r\n\r\n**Aside:**\r\nThat being said, I'm truly blown away (figuratively) by how smooth iron-animated pages and iron-list are on mobile. In a ~1.2 MB app (html & js, pre-gzip), this is one of the few areas that gives away that it could be running non-native. So kudos to the team for that and all the hard work."}}
