Short description of error

Exact steps for others to reproduce the error

Make sure GPU Subdivision is enabled in the preferences
Open attached file or
- With the default Cube go to Vertex Paint Mode
- Paint anything
- Go to shading Workspace
- In the shader add a Attribute Node
- Set "Name" to Col
- Link the Color socket to Base Color
Add Subd modifier to object
Color gets destroyed (thats the sculpt vcolor and normal vcolor)
You can swap the shader attribute to "vert" to test the vertex color or back to "sculpt" to test sculpt vertex color.

Thanks for the report, I can confirm.
@kevindietrich, is this something for you to take a look?

I've fixed this in the sculpt vertex colors patch, don't spend too much time trying to fix it in master.

@JosephEagar Is your fix portable to master though? It would still be nice to have this fixed even if sculpt vertex colors are still experimental.
