Thank you for reporting a bug to Unity. This issue has been fixed in an upcoming release. We have reviewed the issue carefully, and in this case, the team is unable to prioritize backporting this bug to existing releases. 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 a backport may destabilize a release in production. Today we will be closing this port. 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.

Reproduction steps:
1. Open the attached “IN-52580_Sponza 2023 (2).zip“ project
2. Open the “OutdoorsScene”
3. Enter Play mode

Expected result: No flickering white pixel fragments or spots appear
Actual result: White flickering pixel fragments and spots appear

Reproducible with: 2023.2.0b7, 2023.3.0a3
Could not test with: 2021.3.30f1, 2022.3.8f1, 2023.1.11f1 (lighting not working properly and errors after downgrading)

Reproduced on: Windows 11 Pro (22H2)
Not reproduced on: No other environment tested

Notes:

The “Reflection Probe” GameObject is producing the issue and seems to be causing problems with downgrading and stripping the project
Most of the white pixel fragments get blurred by the “Sky and Fog Volume” when Fog is enabled
The fragments that are not blurred are more difficult to see in Game view but they are still there
The fragments are the most visible on the “Details_Door_A001” GameObject but can be seen elsewhere as well
Could not reproduce on a new project
The user’s project seems to be pulled (or at least using the scene or assets) from https://github.com/Unity-Technologies/Classic-Sponza
Could not test with a newly pulled “Classic-Sponza” project due to asset import errors
Unable to strip the project with Repro Project Wizard (lighting not working properly and errors after stripping)
Reproducible in Player
