Assertion failed on expression: Blit to screen in OnRenderImage

Hi!

I am mixing 2 cameras to be able to blur a light renderer (Light is meshes with color gradients) and I'm getting this assertion error

Assertion failed on expression: 'depthSurface == NULL || rcolorZero->backBuffer == depthSurface->backBuffer'


This error happens when calling Blit to null in OnRenderImage, here:

Code (CSharp):

1. private void OnRenderImage( RenderTexture src, RenderTexture dst )
2.     {
3.         if( _cam )
4.         {
5.             _cam.targetTexture = null;
6.         }
7.         Graphics.Blit( src, dst );
8.         Graphics.Blit( dst, null, Material ); //HERE
9.     }

everything works correctly, just the error is very annoying. Do you know why it's happening?

Thanks!

EDIT: The full log error is

I'm having this issue as well, only when I play it on an Android device I think though.
Having trouble finding a solution.....
