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 decisive 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.
This result: VidPN handles and subobjects are generation-bound. A monitor hot-plug, docking action, session switch or mode commit can invalidate an otherwise well-formed cached object. The built-in one-line message identifies the immediate result; diagnosis also needs the producing API, object ownership and the display generation current at the time.
Capture before recreating objects
| Capture item | Why it matters for it |
|---|---|
| Object identity | VidPN object relationship |
| Rejected boundary | handles from different VidPN objects or mode-set owners were combined in one interface call |
| Decisive 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 |
Preserve the unsigned HRESULT, symbolic name, first failing API and timestamp in one record. If cleanup later fails too, keep that secondary result separately from this result.
Reproduce one variable at a time
- Freeze the result generation. Record VidPN handle, topology handle, mode-set handle, source/target IDs and acquisition callback that produced each resource. Before diagnosing this result, do not resize, hot-plug, recreate or release the object under examination.
- Run the narrow it comparison. acquire every object from one VidPN instance and repeat the rejected operation. During the result comparison, keep every driver, monitor, resource format and unrelated policy unchanged.
- Observe the layer after it. for it, if the exact check passes, record the next HRESULT or visible outcome. A different downstream result shows that the boundary was crossed.
- Repeat it through a lifecycle transition. for it, exercise one relevant resize, mode switch, device recreation, hot-plug or session change and confirm that it does not reuse stale handles.
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. Recording both names prevents a broad “graphics error” label from merging distinct ownership, capability and lifetime problems.
Recovery contract
Keep resource provenance with each handle and never mix objects after topology reacquisition. Repair of it is complete only when the original call succeeds or returns its documented nonfatal status and the same lifetime test remains correct after a second display transition.
- The result trace identifies one producing API and one current graphics object, rather than only the final UI symptom.
- The passing run changes exactly the condition described for it; unrelated adapter, monitor and application state remains unchanged.
- debug-layer, ETW or driver diagnostics no longer report the rejected VidPN object relationship contract during the same scenario.
- The application handles recurrence of it without an unbounded retry loop, leaked resource, duplicate composition target or stale topology handle.
Implementation notes
Log source and target IDs, topology generation, path descriptors, pinned modes, mode-set handles and monitor timing data. When the path returns a count, size, status flag or replacement object, retain it even on a nonfatal result because it can direct the next call.
A production fallback for it 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 for it.
