**System Information** Operating system: Windows-10-10.0.19041-SP0 64 Bits Graphics card: AMD Radeon RX 5700 XT ATI Technologies Inc. 4.5.13596 Core Profile Context 20.Q2.1 27.20.1023.1001 **Blender Version** Broken: version: 2.83.4, branch: master, commit date: 2020-08-05 06:00, hash: `rBc113af82881a` **Short description of error** When rendering a mesh with another mesh inside of it and the mesh has a mix glass and transparent shader and there is hair present in the scene then the mesh with the mix glass shader will render incorrectly with opencl compute. CPU Render: {F8770974} CPU +GPU Render: {F8770976} GPU Render: {F8770983} Example Blend File: {F8770987} **Exact steps for others to reproduce the error** Render example Blend file with Opencl GPU and CPU and compare results. Also deleting the hair or deleting the inside cube fixes the Issue.

OR 1. Add mix glass and transparent shader to default cube. 2. Add another cube and give it the default principled shader and scale the cube inside the the default one. 3. Add a plane and give it a Hair particle system and move it to the side. 4. Add an HDRI for some light. 5. Render cpu and opencl gpu and compare results. Also deleting the hair or deleting the inside cube fixes the Issue.
