I´ve isolated it to rendering a specific polygon which is a bit complex. \r\nMy app freezes so it looks like something is blocking the UI thread. \r\n\r\nI´ve attached a sample to reproduce the issue. I´ve tested the same geometry on WPF using both WPF and SKia renderer and it works on WPF, but not on iOS. My observations on the sample running the iOS.\r\n\r\n- On iPad simulator (5 generation iOs 11.4) it seems to freeze like what I see in my real world app\r\n- On physical device it crashes and does not freeze / lock up. So probable due to us having more layers or combined types of layers..\r\n\r\nmy physical device is an iPad Pro running iOS 11.4.\r\n\r\nIts reproduced in MapSui v. 1.4.2. downloaded as .zip from https://github.com/Mapsui/Mapsui/releases \r\nIn our production code we´re using the Nuget package.\r\n\r\nIn the sample substituting one geometry with the other it works/crashes. \r\n\r\nI hope the physical device we sponsored have arrived so it possible to test on a real device - there should be a mail in your gmail account :-).\r\n\r\n[PolygonSampleWKT.zip](https://github.com/Mapsui/Mapsui/files/2123261/PolygonSampleWKT.zip)\r\n"},"comment":{"url":"https://api.github.com/repos/Mapsui/Mapsui/issues/comments/401534058","html_url":"https://github.com/Mapsui/Mapsui/issues/457#issuecomment-401534058","issue_url":"https://api.github.com/repos/Mapsui/Mapsui/issues/457","id":401534058,"node_id":"MDEyOklzc3VlQ29tbWVudDQwMTUzNDA1OA==","user":{"login":"charlenni","id":4381223,"node_id":"MDQ6VXNlcjQzODEyMjM=","avatar_url":"https://avatars2.githubusercontent.com/u/4381223?v=4","gravatar_id":"","url":"https://api.github.com/users/charlenni","html_url":"https://github.com/charlenni","followers_url":"https://api.github.com/users/charlenni/followers","following_url":"https://api.github.com/users/charlenni/following{/other_user}","gists_url":"https://api.github.com/users/charlenni/gists{/gist_id}","starred_url":"https://api.github.com/users/charlenni/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/charlenni/subscriptions","organizations_url":"https://api.github.com/users/charlenni/orgs","repos_url":"https://api.github.com/users/charlenni/repos","events_url":"https://api.github.com/users/charlenni/events{/privacy}","received_events_url":"https://api.github.com/users/charlenni/received_events","type":"User","site_admin":false},"created_at":"2018-06-30T11:04:33Z","updated_at":"2018-06-30T11:04:33Z","author_association":"CONTRIBUTOR","body":"Very good work @pauldendulk !"}}
