We moved back through some previous versions, and found that a build from 16th March worked perfectly ( https://github.com/debrief/debrief/releases/tag/Stable_20150316_3.0.317 )\r\n\r\nJust in case we need to reproduce the problem, here are the specifics of the data:  \r\n* 8 hours of ownship data, with positions on the minute\r\n* 980 sensor cuts, spanning 8 hours\r\n* 3 legs of target track, roughly 2 1/2 hours each\r\n\r\nThe significant changes since then seem to be:\r\n* switch to JFReeChart-SWT  #1169 \r\n* switch from JFreeChart scaling up beyond a certain size to always rendering at native scale\r\n* change to ensure we display the solution's course and speed #1204 \r\n\r\nSteps to reproduce:\r\n* load sample_lots_of_sensors.dpf\r\n* under the Osprey track, switch on the Sensor titled **Sensor:sensor:0 (1505 items)**\r\n* right-click on that sensor, and select **Generate TMA solution from all sensor cuts**\r\n* from the wizard, click on **Next**, then **Finish**\r\n* a new track will appear in the Outline view: **Track:TMA_120532.02**\r\n* make this track the Secondary track (select it, then click on the \"2\" in the Outline toolbar)\r\n* switch to **Drag track segment** view\r\n* start to drag the new red track, you'll see it moves really, really slowly.\r\n\r\nHopefully you'll be able to reproduce the above performance problem, and identify that it doesn't occur in the March builds.\r\n"},"comment":{"url":"https://api.github.com/repos/debrief/debrief/issues/comments/131816874","html_url":"https://github.com/debrief/debrief/issues/1318#issuecomment-131816874","issue_url":"https://api.github.com/repos/debrief/debrief/issues/1318","id":131816874,"user":{"login":"IanMayo","id":1108513,"avatar_url":"https://avatars.githubusercontent.com/u/1108513?v=3","gravatar_id":"","url":"https://api.github.com/users/IanMayo","html_url":"https://github.com/IanMayo","followers_url":"https://api.github.com/users/IanMayo/followers","following_url":"https://api.github.com/users/IanMayo/following{/other_user}","gists_url":"https://api.github.com/users/IanMayo/gists{/gist_id}","starred_url":"https://api.github.com/users/IanMayo/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/IanMayo/subscriptions","organizations_url":"https://api.github.com/users/IanMayo/orgs","repos_url":"https://api.github.com/users/IanMayo/repos","events_url":"https://api.github.com/users/IanMayo/events{/privacy}","received_events_url":"https://api.github.com/users/IanMayo/received_events","type":"User","site_admin":false},"created_at":"2015-08-17T13:21:40Z","updated_at":"2015-08-17T13:21:40Z","body":"Hmm, here's the 317 performance on my machine - it's also slow:\r\n[317_perf.ogv | uploaded via ZenHub](https://files.zenhub.io/55d1dfc44bea290a348bea4d)\r\n"}}
