Thank you for reporting this issue to Unity. We have reviewed the Vulkan validation errors and warnings observed in the URP Sample Scene. While we recognize these messages as valid, the team is unable to prioritize addressing them in the affected versions at this time. This decision considers the issue’s current impact and severity, as well as our future development plans. We will therefore be closing this report. If you encounter a specific rendering issue or other user-visible behavior associated with these validation messages, please submit a new bug report with reproduction steps and supporting materials so that we can investigate it separately. Thank you again for taking the time to report this issue.
Steps to reproduce:
1. Open the attached user's project "reproduce-vvl.zip"
2. Switch to Windows or Android platform and build a Development Build
3. On Android, install the APK on the device and apply the VVL settings via adb
4. Launch the app with -force-vulkan-layers: adb shell am start -S -n com.UnityTechnologies.com.unity.template.urpblank/com.unity3d.player.UnityPlayerGameActivity -e unity "-force-vulkan-layers"
5. Observe logcat
6. On Windows, install Vulkan SDK and place the attached "vk_layer_settings.txt" in the same folder as the .exe
7. Launch from the command line: C:\WindowsBuild> & .\Player.exe -force-vulkan-layers -logFile vvl.log
8. Observe "vvl.log"
Actual result: The following VVL errors/warnings are output every time, right after launch:
SYNC-HAZARD-WRITE-AFTER-READ / MessageID = 0x376bc9df / Error
SYNC-HAZARD-READ-AFTER-WRITE / MessageID = 0xe4d96472 / Error
BestPractices-StoreOpDontCareThenLoadOpLoad / MessageID = 0xa09b0056 / Warning
BestPractices-ImageBarrierAccessLayout / MessageID = 0xf35d019f / Warning
Expected result: No validation errors are outputted
