Hi! I am displaying several polylines in a 2D-View. Unfortunately, an error is thrown everytime I try to rotate the view with the mouse: RangeError: Maximum call stack size exceeded An example to reproduce the problemcan be found [here](https://ppc.paralog.net/showtracks3D.php?event=East+Canada+Wingsuit+Performance+Competition+2016,%20Time,%20Round%201) (switch to 2D, zoom in, rotate…). It works perfectly well in the 3D and 2.5D views. Any ideas what could be going wrong? Thanks, Klaus ---

Hello Klaus, I went to the link you posted but there wasn’t anything on that page. It just said ‘no tracks selected’ -Hannah ---

Aaargh. Stupid hidden post data. Please try [https://ppc.paralog.net/showtracks.php?event=East+Canada+Wingsuit+Performance+Competition+2016&category=Time&round=1](https://ppc.paralog.net/showtracks.php?event=East+Canada+Wingsuit+Performance+Competition+2016&category=Time&round=1) and select the checkbox close to the Cesium icon before clicking it. ---

Thanks Klaus. I was able to reproduce the crash. What version of Cesium is the site using? Could you possibly put together a [Sandcastle](http://cesiumjs.org/Cesium/Apps/Sandcastle/index.html) demo that reproduces the crash? That would make it a lot easier for us to test and figure out what is happening. Thanks! ---

Hi Hanna, I created a stripped down version of the page and in the process removed a rather large library (jqplot) – now I have to rotate the 2D view for quite some time before the error comes up. Unfortunately, I can not put this in Sandcastle due to Same Origin Policies on some resources. You can find it here: [https://ppc.paralog.net/3Dview.html](https://ppc.paralog.net/3Dview.html) Another interesting observation: When I initialize the viewer with ‘sceneMode: Cesium.SceneMode.SCENE2D’ as in [https://ppc.paralog.net/2Dview.html](https://ppc.paralog.net/2Dview.html) , the tracks are not drawn.

Thanks Klaus, I’ve written up an issue here: [https://github.com/AnalyticalGraphicsInc/cesium/issues/4619](https://github.com/AnalyticalGraphicsInc/cesium/issues/4619) -Hannah ---

Klaus, Thanks again for the report, this is a good catch. It was fixed in [#4619](https://github.com/AnalyticalGraphicsInc/cesium/issues/4619) during the bug bash and will be in Cesium 1.31 on March 1. Patrick
