Memory slowly builds up when using "Mesh.SetVertices()" function in Vulkan
How to reproduce:
1. Open the “MeshMemoryLeakIssue.zip“ project
2. Uncheck the “Auto Graphics API for Windows“ in Project Settings > Player > Other Settings
3. In the Project Settings, add the “Vulkan“ Graphics API into the Graphics API list and drag it to the top (then restart the Editor)
4. Open Edit > Build Profiles
5. Enable Development Build and Autoconnect Profiler
6. Build and run the project
7. Hold the left mouse button on the Memory module lines and observe the Profiler window
Expected result: Memory usage does not grow
Actual result: Memory usage is slowly building up
Reproducible in: 2022.3.60f1
Could not test in: 6000.0.42f1, 6000.1.0b10, 6000.2.0a6 (the Player crashes upon launch)
Reproduced on: Windows 11 Pro (24H2), Windows 11 (23H2)
Not reproduced on: No other environment tested
Notes:
- Not reproducible with DX11 and DX12
- Was unable to reproduce the issue in other projects
- Memory increase is also observable in the Task Manager
- I did not look for the fixed in version as it’s likely just an accidental fix, and the bug takes a fairly long time to reproduce after changing versions
