How to reproduce:
1. Open the attached “IN-116550.zip” project
2. Open the “OutdoorsScene”
3. Enter Play Mode
4. Select the “Global Volume” GameObject in the Hierarchy
5. In the Inspector, change the “Max Radius” value in the Near Blur setting
6. Observe the blur of Cube and Canvas GameObjects

Expected result: The blur of both observed GameObjects changes
Actual result: Only the blur of the Cube changes, while the Canvas blur remains unchanged

Reproducible with: 2021.3.45f1, 2023.1.0a1, 6000.0.59f1, 6000.2.7f1, 6000.3.0b4, 6000.4.0a1

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

Note: Canvas blur is only affected if changes in settings also affect the background blur, like the “Max Radius” in the Far Blur setting
