App works fine through instant preview but has major graphical errors in build.

Obviously whatever the camera is recording isn't being rendered in any way. Clear flags are set to Depth Only by ARCore when the app starts so I'm not sure why it looks like clear flags are set to Don't Clear. The next most obvious thing is the screen is mirrored vertically! The scene in the screenshot is literally the vanilla HelloAR scene that comes with ARCore. I haven't made any changes. I'm almost positive the problem isn't the phone (Pixel 2.) It's brand new and I tried some ARCore apps from the Play Store without any issues.




Here's my settings. I've scoured the web looking for the correct settings but maybe I missed something? (I doubt there's a setting that would result in such weird graphical errors tho)

 

Hello,

Are you using any custom shader pipeline like LWRP or HDRP?

if yes, I faced the same issue with LWRP, please downgrade your version to 3.3 or below for LWRP and Test.

Thanks
