ECS RenderMeshSystemV2 has substantial amount of memory leak

Package: Entity Component System (ECS)


How to reproduce:
1. Open the attached project ("") or ( if you have problem opening with latest trunk)
2. Open the repro scene ("SampleScene")
3. Enter Play Mode
4. Inspect Profiler's "Memory" tab

Expected results: Memory usage stays relatively the same
Actual results: Memory usage gradually increases

Reproducible with: 2019.1.2f1, 2019.2.0b1, 2019.3.0a2
Couldn't test with 2017.4 and 2018.4, as they don't support required ECS version
Reproducible with package versions: 0.12-preview.31

After exiting the Play Mode, the allocated memory remains in-use

  1. Resolution Note:

    Fixed in Unity Versions 2019.3.0f6, 2020.1.0a18 and above

    I can confirm this is still in the latest package. Is there any idea of when this will be fixed? Is it yet part of the roadmap for a release?
