Screen Space - Camera UI edges buzz when Temporal Anti-aliasing is enabled and Cinemachine Perlin noise drives the render camera

How to reproduce:

1. Open the attached "IN-152908_UI" project
2. Open the "SampleScene" scene
3. Select the "Main Camera" GameObject and note that "Anti-aliasing" is set to "Temporal Anti-aliasing (TAA)"
4. Select the "Canvas" GameObject and note that "Render Mode" is set to "Screen Space - Camera"
5. Enter Play mode
6. Observe the UI elements in the Game view

Actual result: The edges of the UI elements buzz every frame while the noise is active
Expected result: The UI elements render stably on screen and are not affected by the camera's procedural noise

Reproducible with: 6000.0.0f1, 6000.0.83f1, 6000.3.23f1, 6000.5.11f1, 6000.6.0f1, 6000.7.0a6

Reproducible on: Windows 11
Not reproducible on: No other environments tested

Notes:

• Reproduces in both URP and HDRP. Not reproducible in the Built-in Render Pipeline, which has no TAA option
• The CinemachineBrain "Update Method" does not change the result
