Reproduction steps:
1. Open the attached “ASDQWE” project
2. Open the “Assets/_Scenes/demo_test_2.unity” Scene
3. In the Hierarchy Window, select “_EFFECTS > IE_Main” GameObject
4. In the Inspector Window, enable the Bloom effect “Volume > Bloom”
5. Open Task Manager (or Activity Monitor)
6. Enter the Play Mode
7. In the Task Manager, observe the Unity process

Expected result: The Unity process’s memory usage remains stable
Actual result: The Unity process’s memory usage steadily rockets

Reproducible with: 2023.2.0b4, 2023.2.0b15, 2023.3.0a8
Not reproducible with: 2021.3.30f1, 2022.3.10f1, 2023.2.0a1
Fixed in: 2023.3.0a9

Could not test with: 2023.1.15f1, 2023.2.0a2 - 2023.2.0b3 (Game View is dark with only UI visible and the Console Window is spawned with warnings and errors)

Reproducible on: Intel macOS 13.5
Not reproducible on: No other environment tested

Notes:

• Exiting the Play Mode does not release the used memory

• In the 2023.2.0b4-2023.2.0b6 versions, the increase in memory usage is the most visible

• Starting from 2023.2.0b7 the memory usage increase is not so drastic and the overall usage fluctuates and is unstable
