Exception when loading too many data

Hello,

i’m trying to build a chart using a Stripe Data series, on the X axis i have a DatetimeAxis while on Y axis i have a Numeric.

I have an observable collection of IRenderableSeriesViewModel, and when i try to add a StripeRenderableSeriesViewModel if the dataseries contains many elements (>2000) it logs this exception below:

Exception thrown: ‘System.InvalidCastException’ in System.Private.CoreLib.dll
SciChartSurface didn’t render, because an exception was thrown:

Binding and data i’m pretty sure are ok since with fewer data it works fine

EDIT: i was able to reproduce the issue in the wpf sample project (repo), just replace GanttChartViewModel.cs with the sample one i have attached here and it can be reproduced by navigating to the Gantt chart example
