With v 1.55 2004/10/11 16:09:50 everything works as expected: On the first slide, the full second line is shown in transparent style. This seems similar to issue #87 .\r\n\r\nThe same happens if I use plain TeX's `\\halign`, so cases is not the culprit. Moreover, if I don't use `\\setbeamercovered{transparent}`, then everything works as expected. In other words, `\\pause` doesn't work together with `\\setbeamercovered{transparent}` and `\\halign`.\r\n\r\nI've also posted the issue here: http://tex.stackexchange.com/q/6348/1235\r\n\r\n----------------------------------------\r\n- Bitbucket: https://bitbucket.org/rivanvx/beamer/issue/106\r\n- Originally reported by: Anonymous\r\n- Originally created at: 2011-01-05\r\n"},"comment":{"url":"https://api.github.com/repos/josephwright/beamer/issues/comments/85377291","html_url":"https://github.com/josephwright/beamer/issues/106#issuecomment-85377291","issue_url":"https://api.github.com/repos/josephwright/beamer/issues/106","id":85377291,"user":{"login":"josephwright","id":654518,"avatar_url":"https://avatars.githubusercontent.com/u/654518?v=3","gravatar_id":"","url":"https://api.github.com/users/josephwright","html_url":"https://github.com/josephwright","followers_url":"https://api.github.com/users/josephwright/followers","following_url":"https://api.github.com/users/josephwright/following{/other_user}","gists_url":"https://api.github.com/users/josephwright/gists{/gist_id}","starred_url":"https://api.github.com/users/josephwright/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/josephwright/subscriptions","organizations_url":"https://api.github.com/users/josephwright/orgs","repos_url":"https://api.github.com/users/josephwright/repos","events_url":"https://api.github.com/users/josephwright/events{/privacy}","received_events_url":"https://api.github.com/users/josephwright/received_events","type":"User","site_admin":false},"created_at":"2015-03-24T07:36:13Z","updated_at":"2015-03-24T07:36:13Z","body":"Retesting, this is fine with an up-to-date `beamer`: INVALID."}}
