ZTest only works in compatibility mode in Unity 6.3LTS URP

In Unity 6000.3.0f1 in a URP project, ZTesting appears not to work (equivalent to Always passing) unless I define URP_COMPATIBILITY_MODE and enable Compatibility Mode (Render Graph Disabled) in the graphics settings. They seem to be phasing out the non render graph URP so would be great to have this addressed. Or at least just appear in the warning in the Shapes UI and a quick-fix button.

Cheers
