Question Unwanted white pixel artifact along mesh edges when in front of a transparent URP material

Hi,
I'm getting an unwanted white/grey pixel outline along the edges of a mesh when it is in front of an object with a transparent material (in URP 14.06). The mesh's material does not use a texture.

Below is a mesh with an unlit material in front of a URP lit shader set to Transparent:


Below is the same mesh in front of a URP lit shader set to Opaque:


This white/grey outline effect is more clearly visible if I turn off anti-aliasing and remove cell shading from the shader:


Any tips on where I could look to minimize this would be greatly appreciated.

Thanks,
Daniel
