These are very clear during normal playback, especially in some transition or in subtitles (using blend-subtitles).\r\nCan't say anything about other tscales because I've always used only oversample, but the latter's \"old version\" for sure didn't suffer from this.\r\nHere's a sample file in which the problem shows up clearly: http://a.pomf.cat/ndkqmf.mkv\r\nAnd here's some screen of the problem I've attained recording the screen during playback: http://imgur.com/a/sE1Ft\r\nLet me know if you need any other sample/info/log."},"comment":{"url":"https://api.github.com/repos/mpv-player/mpv/issues/comments/122563511","html_url":"https://github.com/mpv-player/mpv/issues/2155#issuecomment-122563511","issue_url":"https://api.github.com/repos/mpv-player/mpv/issues/2155","id":122563511,"user":{"login":"haasn","id":1149047,"avatar_url":"https://avatars.githubusercontent.com/u/1149047?v=3","gravatar_id":"","url":"https://api.github.com/users/haasn","html_url":"https://github.com/haasn","followers_url":"https://api.github.com/users/haasn/followers","following_url":"https://api.github.com/users/haasn/following{/other_user}","gists_url":"https://api.github.com/users/haasn/gists{/gist_id}","starred_url":"https://api.github.com/users/haasn/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/haasn/subscriptions","organizations_url":"https://api.github.com/users/haasn/orgs","repos_url":"https://api.github.com/users/haasn/repos","events_url":"https://api.github.com/users/haasn/events{/privacy}","received_events_url":"https://api.github.com/users/haasn/received_events","type":"User","site_admin":false},"created_at":"2015-07-18T16:50:27Z","updated_at":"2015-07-18T16:50:27Z","body":"Most of those screenshots just look like it's working as intended. You could try posting a playback log with ```msg-level=vo=debug``` with both the old and new versions of oversample.\r\n\r\nThat said, the one that confuses me is the one where the afterimage is “black”. I'm not sure how that could even possibly happen, given the fact that it's just blending two images together, not subtracting or anything."}}
