CallbackOnCollectedDelegate when draving

[Vodacek]

Hi I am having some trouble with running my game. After year I have updated MonoGame to latest develop version. When in my game I look at specific location (I am using frustrum culling) I got this error:

CallbackOnCollectedDelegate occurred
Message: Managed Debugging Assistant 'CallbackOnCollectedDelegate' has detected a problem in 'xyz'.
Additional information: MonoGame.Framework!OpenGL.GL+DebugMessageCallbackProc::Invoke

in Microsoft.Xna.Framework.Graphics.GraphicsDevice.PlatformDrawIndexedPrimitives(PrimitiveType primitiveType, Int32 baseVertex, Int32 startIndex, Int32 primitiveCount) in \MonoGame\MonoGame.Framework\Graphics\GraphicsDevice.OpenGL.cs:line1021

I am using DesktopGL on Windows 10 machine. Anyone experiencing same issue?

Maybe this old problem topic i had will help. Since this is most likely has to do with the custom vertice structure declaration.

[SOLVED] Strange custom vertex data fx problem

Im seeing something that i really don’t understand with my shader, when i add a normal to my custom vertice data structure, then send it to my .fx shader shown below (which doesn’t really do anything) i get problems. //_______________________________ // PNCMT PosNormalColorMultiTexture fx #if OPENGL #define SV_POSITION POSITION #define VS_SHADERMODEL vs_3_0 #define PS_SHADERMODEL ps_3_0 #else #define VS_SHADERMODEL vs_4_0_level_9_1 #define PS_SHADERMODEL ps_4_0_level_9_1 #endif float4x4 gworld…

Your error at Line 1021 is here below.

        GL.DrawElements(target, indexElementCount, indexElementType, indexOffsetInBytes);

The code can be found here on git hub.
