使用Windows远程桌面连接时触发OnRenderSurfaceBaseLoaded空引用异常

I'm hitting a frustrating NullReferenceException in SciChart whenever I connect to my Windows 10 application using Remote Desktop, and I’m stuck figuring out how to fix it. Here’s a full breakdown of the situation:

• Affected SciChart Versions: v4.2.3.10193 and v5.1.0.11299
• Environment: Windows 10
• Trigger: The exception is thrown immediately upon establishing a Remote Desktop connection to the machine running the app

Exception Stack Trace #

What I’ve Tried So Far #

1. Disposing Render Surface: I attempted to resolve potential memory leaks from LinearGradientBrush in our CustomRenderableSeries by explicitly disposing the render surface with this code:

if(scs.GetValue(SciChartSurfaceBase.RenderSurfaceProperty) is IRenderSurface renderSurface) 
    renderSurface.Dispose();

2. Checking Existing Solutions: I looked into a previously reported issue related to Direct3D null references, but the suggested fixes didn’t work for the v5.1.0.11299 version.

I’m at a loss for what to try next. Has anyone encountered this exact problem with SciChart over Remote Desktop, especially with the v5.x versions? Any workarounds or insights would be greatly appreciated.
