Error when instantiating compute shader

I'm getting an error while instantiating a compute shader with:

Code (csharp):

1.  
2. var shader = Instantiate(ShaderPrefab);
3.  

Error:

Code (csharp):

1.  
2. !(transfer.IsRemapPPtrTransfer() && transfer.IsReadingPPtr())
3. UnityEngine.Object:Instantiate(ComputeShader)
4.  

What is interesting, shader seems to work fine and no issues are noted.
Is it a bug?

 

Same error for me when doing :

Code (CSharp):

1. ComputeShader convertCS = Instantiate(Resources.Load("ConvertShader")) as ComputeShader;

Compute shader is working well when manually assigned in editor.

 

Strange this is that shader works fine even with this error message. Or at least seems to be working fine...

 

It seems that shader created that way sometimes fail to work (can't debug it precisely yet).

 

Bump?
Still got it in 5.4.

 

interestingly i get the same error when running the demo scene for the Hair Tool, https://www.assetstore.unity3d.com/en/#!/content/66094

Same problem in Unity 2017 beta 1.

Code (CSharp):

1. Assertion failed: Assertion failed on expression: '!(transfer.IsRemapPPtrTransfer() && transfer.IsReadingPPtr())'

How to deal with this? The compute shader runs a particle system and I need multiple instances, otherwise I will have to upload all properties every frame.

 

This is still an issue in Unity 2017.1.0f3.

 

That's true

 

Still an issue in Unity 2017.3.0b10.

 

Same in 2018.1.0b1

 

Same result in 2017.3.0p3

 

Same in 2018.1.b10.

Here's one of the bug reports about his:
https://issuetracker.unity3d.com/is...is-thrown-when-instantiating-a-compute-shader

@Aras I don't think it's super polite to tag you here, but that message spams the Editor in ComputeShader-heavy applications – do you know what's going on here?

 

Same in 2018.1.0b12.

My project console is spammed with 15 error messages every time I run. All from ComputeShaders. It is becoming a huge annoyance.

EDIT: The issue linked to above is marked as "Fixed in Unity 2018.2". Thats a long wait =(

EDIT2: I downloaded the Unity 2018.2 beta and the errors are gone! Yah! =D
