How to reproduce:
1. Open the attached project “TAASponza.zip“
2. Open Scene “Sponza“ (Assets/SponzaHDRP/Scenes)
3. Drag and drop the “SponzaLightingDay” Scene into the Hierarchy
4. Select the “Camera_1“ GameObject in the Hierarchy (child of the “Cameras” GameObject)
5. Focus on the Game view window
6. In the Camera Component of the “Camera_1“ GameObject go to “Rendering“ and change “Post Anti-aliasing” from “Temporal Anti-aliasing“ to “No Anti-aliasing“

Expected result: Anti-aliasing turns off
Actual result: Anti-aliasing effects remain

Reproduced on: macOS (12.5)

Note:
- For the issue to be easier to see, in the Game view, change the scale from “1x“ to “10x“
- Issue also effects other TAA options (e. g. when “Sharpening Mode” is set to “Low quality“)
