Blender Version
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-06-25 20:57, hash: 5759bbe9f9
Worked: (newest version of Blender that worked as expected)

Short description of error
Using any modifier in the modifier stack after a GN node modifier which uses point instance node will destroy all the UVs on the given object.
Before:

After:

Exact steps for others to reproduce the error

Distribute any meshes with textures utilizing UVs using Point Instance node onto another mesh
Apply any modifier after the previous GN node network modifier.
Result: UVs get destroyed
Expected: UVs do not get destroyed

Thanks for the report.

The task I merged this into is a bit different on the user level, but the issue is the same. Basically EEVEE doesn't support rendering with generic attributes (rather than the special legacy kind of UV data) at the moment, which is what geometry nodes outputs.

The situation isn't ideal, since it comes from the transition between two systems, but IMO this is more of a TODO.

BTW, this also applies to the other similar report you also just submitted.

Is there any workaround at the moment?
