Thank you for reporting a bug to Unity. We have reviewed the issue carefully, and in this case, the team is unable to prioritize fixing this bug. There are a number of reasons we make this decision, including the impact and severity of the issue across our user and customer base, and the possibility that future plans may solve the problem in a different way, or that a workaround for the bug may be available. Today we will be closing this case. Thank you again for taking the time to report this issue, and please let us know if there is anything else that changes the impact or severity of this issue.

Steps to reproduce:
1. Open the attached user's project "Frustum.7z"
2. Open the "OutdoorScene.unity" Scene and enter Play Mode
3. Observe the Game View

Actual results: directional light shadow cascades are visibly clipped. Shadows disappear in portions of the view that fall outside what a symmetric frustum would cover
Expected result: directional light shadow cascades are not clipped

Reproducible with: 6000.0.70f1, 6000.3.9f1, 6000.4.0b11, 6000.5.0a8

Environment tested: Windows 11 25H2

Notes:
-Using nonObliqueProjectionGetter didn't solves the problem. Modifying the cascades distance and the shadow distance in the shadow override of the Volume works as a workaround.
-The camera's frustum is modified via the Frustum component found in the "camera" GameObject
-Change the if condition in Frustum.cs "UpdateFromViewport" to enable the use od nonObliqueProjectionGetter
