VRAM usage is constantly increasing when generating procedural textures and building bundles with Vulkan

-

How to reproduce:
1. Open the “Archive.zip“ project through the CLI with the “-force-vulkan“ argument
2. Open the Task Manager
3. Select the “Texture Creator Settings.asset“ ScriptableObject
4. Change the “Textures“ value to 1000 in the Inspector
5. Start generating textures by clicking on “UnitySupport > Create Textures” in the Toolbar
6. Observe the Task Manager

Additionally:
7. Start building bundles by clicking on “Bundles > Build“ after the generation is done
8. Observe the Task Manager

Expected result: VRAM usage is constant while generating textures and building bundles
Actual result: VRAM usage keeps increasing throughout the texture generation and the bundle-building process

Reproducible in: 2021.3.46f1, 2022.3.531, 6000.0.29f1, 6000.1.0a6

Reproduced on: Windows 11 Pro (23H2), Windows 10 (By the reporter)
Not reproduced on: No other environment tested

Notes:
- Reproducible only with the Vulkan Graphics API
- For almost every texture, there will be a “Vulkan - Suboptimal memory type used for image because of low memory.“ warning displayed after the generation
- After generating textures and building the bundles the memory is released
- With DirectX, GPU usage does not climb over 4 GB usage
