[Here](https://youtu.be/SeV1MyKY9yA)'s a little demo, and [this](https://gist.github.com/9800a49c2d77d821daee) is the file I was testing with. The effect seems greater when there are either more characters in a split (with a more \"dense\" file and/or smaller font), when the split is scrolled more quickly, or both.\r\n\r\n![screenshot](https://cloud.githubusercontent.com/assets/2074322/11924601/16651dca-a781-11e5-94a1-2faee7dd2307.png)\r\n\r\nI have tested with gnome-terminal, st, and xfce4-terminal, and it occurs in all of them, so I don't think the terminal is at fault. I've also managed to reproduce this with an empty init.vim."},"comment":{"url":"https://api.github.com/repos/neovim/neovim/issues/comments/171294683","html_url":"https://github.com/neovim/neovim/issues/3875#issuecomment-171294683","issue_url":"https://api.github.com/repos/neovim/neovim/issues/3875","id":171294683,"user":{"login":"synaptiko","id":1593280,"avatar_url":"https://avatars.githubusercontent.com/u/1593280?v=3","gravatar_id":"","url":"https://api.github.com/users/synaptiko","html_url":"https://github.com/synaptiko","followers_url":"https://api.github.com/users/synaptiko/followers","following_url":"https://api.github.com/users/synaptiko/following{/other_user}","gists_url":"https://api.github.com/users/synaptiko/gists{/gist_id}","starred_url":"https://api.github.com/users/synaptiko/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/synaptiko/subscriptions","organizations_url":"https://api.github.com/users/synaptiko/orgs","repos_url":"https://api.github.com/users/synaptiko/repos","events_url":"https://api.github.com/users/synaptiko/events{/privacy}","received_events_url":"https://api.github.com/users/synaptiko/received_events","type":"User","site_admin":false},"created_at":"2016-01-13T13:44:50Z","updated_at":"2016-01-13T13:44:50Z","body":"I've noticed similar thing recently but when switching between tabs...\r\n\r\n![screenshot from 2016-01-08 16-31-48](https://cloud.githubusercontent.com/assets/1593280/12295847/2d7b53cc-ba04-11e5-9774-1046ab72662a.png)\r\n"}}
