Hello,
There's an issue that's been reported where you can see significant flicker and artifacting in Unity applications after dropping to the home menu and then returning to the app. You should be able to avoid the problem by ensuring that the depth submission mode in OpenXR project settings is set to 16 bit. See this post for details- Unity Resume Glitching/Strobing ML2 - #6 by kbabilinski
The problem has been reported with Unity version 2022.3.46f1 - 50f1 which is the latest. It sounds like just ensuring that the depth submission mode is set correctly should be sufficient, but please let us know if you see any problems. I don't think you need to downgrade unless issues occur.
Best,
Adam
