You can often see that animations are slightly stuttering on any device & chrome version after you open a modal/popup. The performance often goes back to it's normal state after a while and sometimes don't which is a real problem, on lower-end device this performance hit is NOT negligible at all.\r\n\r\nThis bug was probably introduced when the popup/modal system was added which is quite old."},"comment":{"url":"https://api.github.com/repos/angular/material2/issues/comments/329635612","html_url":"https://github.com/angular/material2/issues/6882#issuecomment-329635612","issue_url":"https://api.github.com/repos/angular/material2/issues/6882","id":329635612,"user":{"login":"Ploppy3","id":7990765,"avatar_url":"https://avatars2.githubusercontent.com/u/7990765?v=4","gravatar_id":"","url":"https://api.github.com/users/Ploppy3","html_url":"https://github.com/Ploppy3","followers_url":"https://api.github.com/users/Ploppy3/followers","following_url":"https://api.github.com/users/Ploppy3/following{/other_user}","gists_url":"https://api.github.com/users/Ploppy3/gists{/gist_id}","starred_url":"https://api.github.com/users/Ploppy3/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Ploppy3/subscriptions","organizations_url":"https://api.github.com/users/Ploppy3/orgs","repos_url":"https://api.github.com/users/Ploppy3/repos","events_url":"https://api.github.com/users/Ploppy3/events{/privacy}","received_events_url":"https://api.github.com/users/Ploppy3/received_events","type":"User","site_admin":false},"created_at":"2017-09-14T23:26:06Z","updated_at":"2017-09-14T23:26:06Z","author_association":"NONE","body":"@crisbeto You should really do something about the plunkers, It takes time to code them and they always break within a few days."}}
