How to reproduce:
1. Open the user-attached “Flicker.zip” project
2. Open the “SampleScene” Scene (Assets/Scenes folder)
3. Move the mouse over the Scene View or move around in the Scene

Expected result: The Wireframe mesh is not flickering in the Scene View
Actual result: The Wireframe mesh constantly flickers in the Scene View

Reproducible with: 2020.3.36f1, 2021.3.5f1, 2022.1.8f1, 2022.2.0a18, 2023.1.0a2

Reproduced on: macOS Monterey 12.0.1

Note:
- On 2022.1, 2022.2, and 2021.3 the Wireframe Mesh flickering is not as obvious (harder to see)
- RP packages are being used in the project, but they have no effect on reproduction
