How to reproduce:
1. Open the attached “IN-127332” project
2. Open the “StreamingMipmapTestScene”
3. Enter Play mode
4. Click the “Use Quality High” checkbox, in the Game view, to swap between High and Low Quality setting
5. Observe the Game view

Actual result: Both GameObjects at the top remain visibly lower fidelity
Expected result: All four GameObjects appear the same high fidelity

Reproducible on: 2023.1.0a3, 6000.0.65f1, 6000.3.3f1, 6000.4.0b3, 6000.5.0a4

Reproducible with: macOS 26.2 (M1 Pro), Windows 11 (by the user)
Not reproducible with: No other environments tested

Notes:
- Two GameObjects at the top use Particle Renderer, while the ones at the bottom use Mesh Renderer
- Does not reproduce when the same exact material is used for Particle and Mesh renderers, in the example two materials are used, both derived from the same texture with identical settings
- The issue stops reproducing in the Editor, if the materials used are selected in the Project window, reopening the project or building a Player will cause the issue to reproduce again
- Also reproducible in Player
