VRAM Leak when using RendererExtensions.updateGIMaterials()
How to reproduce:
1. Open users’ attached “vramtest.zip” project
2. Open Scene “SampleScene”
3. Open the Profiler window (Window -> Analysis -> Profiler)
4. Change the Profiler Modules so that only the ‘Rendering' Module is displayed
5. In the Hierarchy select GameObject “Cube” and in the Inspector enable the “Updategimaterials” script
6. Enter the Play Mode and observe RenderTextures memory usage in the Profiler
Expected results: RenderTextures memory stays constant
Actual results: RenderTextures memory keeps constantly increasing
Reproducible with: 2019.4.29f1, 2020.2.0a2
Not reproducible with: 2019.4.30f1, 2020.2.0a3, 2020.3.16f1, 2021.1.16f1, 2021.2.0b7, 2022.1.0a5
Notes:
- To observe expected results repeat steps 5-6 with the “Updategimaterials” script disabled.
-
Resolution Note (2019.4.X):
Fixed in 2019.4.30f1, 2020.2.0a3, and above

Please backport this fix to 2019.4 LTS. As others have said, this is a commonly used feature in VRChat. And looking at VRChat's release schedule and the number of breaking changes to VR in 2020; due to this bug it is unlikely UGC will be able to use realtime GI for at least a year, if not more.

This fix should definitely be backported to LTS versions.

This needs to be fixed in older LTS versions of unity as well! Present in 2019.4.29f1.

Please backport this fix to Unity 2019 LTS for VRChat users. It has a large impact there.
