ERROR_GRAPHICS_RESOURCES_NOT_RELATED
Interpret the result in its owning layer: graphics resources not related
ERROR_GRAPHICS_RESOURCES_NOT_RELATED (0xC0262330) belongs to the vidpn layer. It marks handles from different VidPN objects or mode-set owners were combined in one interface call, rather than a generic rendering failure. The object that owns the decision is VidPN object relationship.
Handle provenance is the useful test
A VidPN interface can expose topology, source-mode-set and target-mode-set objects that look structurally compatible but still belong to different parent objects. Record the callback that acquired each handle, the parent VidPN identity and the endpoint ID. Reacquiring only one subobject after a topology change creates exactly the mixed-generation condition that this result is intended to reject. A good regression test labels every handle with its parent and generation before any assign, release or path-enumeration call.
Capture before recreating objects
| Capture item | Why it matters |
|---|---|
| Object identity | VidPN object relationship |
| Rejected condition | handles from different VidPN objects or mode-set owners were combined in one interface call |
| What to capture | VidPN handle, topology handle, mode-set handle, source/target IDs and acquisition callback that produced each resource |
| Current graph state | VidPN, topology, source and target mode sets, and the present path connecting them |
| Supporting trace | source and target IDs, topology generation, path descriptors, pinned modes, mode-set handles and monitor timing data |
Reproduce one variable at a time
- Capture the failing state. Record VidPN handle, topology handle, mode-set handle, source/target IDs and acquisition callback that produced each resource.
- Acquire every object from one VidPN instance and repeat the rejected operation.
The comparison with ERROR_GRAPHICS_STALE_VIDPN_TOPOLOGY is especially useful: ERROR_GRAPHICS_STALE_VIDPN_TOPOLOGY concerns an old topology from the same logical adapter.
Recovery contract
Keep resource provenance with each handle and never mix objects after topology reacquisition.
- debug-layer, ETW or driver diagnostics no longer report the rejected VidPN object relationship contract during the same scenario.
Implementation notes
Log source and target IDs, topology generation, path descriptors, pinned modes, mode-set handles and monitor timing data.
A production fallback should be explicit: pause rendering, re-enumerate, rebuild one cache entry, recreate a device, or decline a protected path only when this layer calls for that action. Reinstalling every display component, deleting all caches or forcing a resolution change is not an evidence-based fix.
