System Information
Operating system: Win11
Graphics card: rtx3050

Blender Version
Broken: (blender-3.2.0-beta+v32.e86b62f1951b-windows.amd64-release)
Worked: (3.1 release)

Caused by eae36be372

Short description of error

Using a color attribute created with geometry nodes on the face or edge domains no longer works with Eevee. It does work in Cycles and this does work in Eevee in 3.1 release versions. If the color attribute is on the point domain or face corner domains it works fine in Eevee in 3.2 beta.

An additional (possibly related) bug that I noticed when testing this is that Cycles does not show color attributes if they are on the edge domain. This occurs in 3.1 and 3.2 beta. The edge domain does work in Eevee in 3.1 only.

Exact steps for others to reproduce the error

Open up the blend file and change the domain of the color attribute on the group output node. It works for Eevee for point and face corner domains but not face or edge domains. Now try it in Cycles and it works for point, face, face corner domains, but not edge.

Wasnt aware this was working in 3.1.
Not sure if it is supposed to be supported actually, will check (also when this changed).

This has changed in eae36be372.
A bit unsure if this is supposed to be supported, but if it is, then this might be a regression.

This was working in Eevee for the early 3.2 alphas, in the same way as 3.1. I am guessing that the new sculpt colors and color attributes broke it.

Edge domain doesn't work for Cycles in 3.1 or 3.2, but it does in 3.1 Eevee. Not something you would use very often, but there should be consistency between Eevee and Cycles for all 4 domains.

Until further info on this, this looks like a regression (and at least personally I think at least support for Face Domain is very useful)
