System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce RTX 2070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 461.40

Blender Version
Broken: version: 2.92.0, branch: master, commit date: 2021-02-24 16:25, hash: 02948a2cab
Worked: never, as far I can tell, tested as far as 3.0 alpha and 2.93 beta

Short description of error
When I'm trying to change some parameters in material that is library overrided from another file it keeps changing it's value to a default material values of it's linked parent file.

Exact steps for others to reproduce the error

Download two parent.blend and linked_material.blend, keep them in the same directory to prevent error from linking
linked_material.blend
parent.blend
Open linked_material.blend
Try to change parameter on material that has library override enabled. I assume that color should be changed (You can see this at least in small icon in material list but nothing in viewport or anywhere)

Hi and thx for the report! (sorry it took quite a while to answer)

Node materials are still marked as more or less unsupported in #73318 (Library overrides)
I can see some (non-nodal) support though, see 162c320a75 (so e.g. everything in Viewport Display works fine)

Asked in chat, and unfortunately this is expected behavior atm.

overrides should work as in, overrides of ID pointers (which matters especially for tricks like drivers and such).
But no property (setting) is overridable currently.
So yeah... kind of intermediate state until we decide what is or is not overridable in nodes. No real nice way to convey that to users unfortunately

Afraid we have to close this for now, thx reporting again!
