DrawMeshInstancedIndirect not working in Hololens2
Using the DrawMeshInstancedIndirect sample code from the docs on a clean 2020.3.30f1 OpenXR project following the Microsoft recommended setup and the instance geometry is only rendered in the left eye while normal models are rendered correctly in both. Appears to be an issue with the Single Pass Stereo Rendering being used with this. Any suggestions on how to fix this (without resorting to slow multi-pass rendering)?

Can anyone explain what this statement in Single Pass Instanced rendering docs means as I think it may be relevant.
Procedural geometry: When using the Graphics.DrawProceduralIndirect() and CommandBuffer.DrawProceduralIndirect() methods to draw fully procedural geometry on the GPU, it is important to note that both methods receive their arguments from a compute buffer. This means that it is difficult to increase the instance count at run time. To increase the instance count, you need to manually double the instance count contained in your compute buffers.
See Vertex and fragment shader examples for more information on how to write shader code.
