(Again: https://github.com/NativeScript/NativeScript/issues/7125)\r\n\r\nYou have to change background colors of elements while navigating to a new route several times. After a while it crash.\r\n\r\nUse case: Change background color of current route in a menu.\r\n\r\n* It don’t crash when you only navigating\r\n* It don’t crash when you only change background color\r\n* It crash when you do both\r\n* It don’t crash when you change text color instead of background color\r\n* It crash quicker when you do lot of calculations in the app\r\n\r\n**To Reproduce**\r\n\r\n* Navigate to a new route every second (router.navigate)\r\n* Change Background color of current route in the menu ([class.active]=« … »)\r\n* Overloading the app with other changes (Here other background color changes) (Necessary to accelerate the crash)\r\n\r\n**Expected behavior**\r\nNo crash.\r\n\r\n**Sample project**\r\nhttps://play.nativescript.org/?template=play-ng\u0026id=4RKa1j\u0026v=2\r\nDownload it, add \"markingMode\": \"none\" in app/package.json under « android » object\r\nYes, it don’t crash directly in PlayGround.\r\n\r\n**Additional context**\r\nObserved on my application and reproduced in a blank application.\r\nIn my app it can crash after 3 or 40 route changes.","author":{"url":"https://github.com/jpierront","@type":"Person","name":"jpierront"},"datePublished":"2019-07-26T22:08:14.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":27},"url":"https://github.com/7867/NativeScript/issues/7867"}
