HDRP Sun's bloom jitters significantly and becomes square when Dynamic Resolution decreases
Reproduction steps:
1. Open the attached “IN-98922.zip” project
2. Open the “OutdoorsScene” Scene
3. Enter Play mode
4. In the Game view, move the mouse cursor up and down
5. Observe the Sun’s bloom change
Expected result: The Sun’s bloom transition between different dynamic resolutions is not significantly different
Actual result: The Sun’s bloom transition between different dynamic resolutions is significantly different and Sun becomes more square as the resolution gets lower

Resolution Note:
This is a fundamental limitation of the bloom technique with extremely bright and very small objects subject to aliasing when changing rendering resolution. We recommend using larger values for the Angular Diameter of the Sun object to alleviate the aliasing and thus flickering issues, along with some experimentation with Flare Size & Flare Falloff that fits the use scenario.
