Steps to reproduce:
1. Open a project with HDRP
2. Set Graphics API to Vulkan (Edit -> Project Settings... -> Player -> Other Settings -> Rendering)
3. Create a Material that uses HDRP/Lit shader
4. Set the Material's Surface Type to Opaque
5. Create a GameObject and add a Mesh Renderer Component
6. Add the Material with the Opaque Surface Type to the Mesh Renderer
7. Duplicate the GameObject with the Mesh Renderer a couple times
8. Click on different GameObjects with the Mesh Renderer so they would be displayed in the Inspector

Expected results: Unity doesn't lag or crash
Actual results: Unity freezes, lag spikes and/or crashes

Reproducible with: 2019.3.0a6 (HDRP 5.16.1), 2019.2.15f1 (HDRP 6.9.0, 6.9.2), 2019.3.0a11 (HDRP 7.0.0), 2019.3.0b4 (HDRP 7.0.1, 7.1.1, 7.1.2)
Not reproducible with: 2019.3.0a6 (HDRP 5.13.0), 2020.1.0a14 (HDRP 7.1.5, 7.1.6)

First 3 lines of the stacktrace:
0x00007FFC9762F2EF (nvoglv64) vkGetInstanceProcAddr
0x00007FFC976236FF (nvoglv64) vkGetInstanceProcAddr
0x00007FFCEA0FC1C4 (vulkan-1) vkDestroyDescriptorPool

Notes:
- Unity might freeze or lag after the 4th step since displaying the Material in the Inspector also gives a repro
- Unity crashes without freezing or lag spikes on HDRP 5.16.1, 7.1.2
