The best way to reproduce this is the set the source limit to say level 14 and then zoom in to 15 or beyond as this will exaggerate the edge alignment.  The image above was captured at level 14 on a source level 14 setup so it can be seen at the non over-zoomed level in the right set of circumstances.\r\n\r\nJust to be sure I setup the @sdlime provided demo and set the maxzoom to 7 for the style and was able to capture this at level 8 from the demo data:\r\n![capture1](https://user-images.githubusercontent.com/1870615/40524333-a05cdb26-600c-11e8-9bab-a1c4a97f0c93.JPG)\r\n\r\nThere may be a buffer issue that is causing this and I cannot workout how to use the buffer increase/decrease function the is provided - any help on this would be appreciated."},"comment":{"url":"https://api.github.com/repos/mapserver/mapserver/issues/comments/394797442","html_url":"https://github.com/mapserver/mapserver/issues/5596#issuecomment-394797442","issue_url":"https://api.github.com/repos/mapserver/mapserver/issues/5596","id":394797442,"node_id":"MDEyOklzc3VlQ29tbWVudDM5NDc5NzQ0Mg==","user":{"login":"alexandreleroux","id":874004,"node_id":"MDQ6VXNlcjg3NDAwNA==","avatar_url":"https://avatars0.githubusercontent.com/u/874004?v=4","gravatar_id":"","url":"https://api.github.com/users/alexandreleroux","html_url":"https://github.com/alexandreleroux","followers_url":"https://api.github.com/users/alexandreleroux/followers","following_url":"https://api.github.com/users/alexandreleroux/following{/other_user}","gists_url":"https://api.github.com/users/alexandreleroux/gists{/gist_id}","starred_url":"https://api.github.com/users/alexandreleroux/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/alexandreleroux/subscriptions","organizations_url":"https://api.github.com/users/alexandreleroux/orgs","repos_url":"https://api.github.com/users/alexandreleroux/repos","events_url":"https://api.github.com/users/alexandreleroux/events{/privacy}","received_events_url":"https://api.github.com/users/alexandreleroux/received_events","type":"User","site_admin":false},"created_at":"2018-06-05T17:39:22Z","updated_at":"2018-06-05T17:39:22Z","author_association":"NONE","body":"Hi Steve, that's a single WMS call displayed in QGIS 2.
