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.

ERROR_GRAPHICS_RESOURCES_NOT_RELATED: VidPN handles and subobjects are generation-bound. For ERROR_GRAPHICS_RESOURCES_NOT_RELATED, A monitor hot-plug, docking action, session switch or mode commit can invalidate an otherwise well-formed cached object. For ERROR_GRAPHICS_RESOURCES_NOT_RELATED, 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 `ERROR_GRAPHICS_RESOURCES_NOT_RELATED`
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

For ERROR_GRAPHICS_RESOURCES_NOT_RELATED, 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 ERROR_GRAPHICS_RESOURCES_NOT_RELATED.

Reproduce one variable at a time

Freeze the ERROR_GRAPHICS_RESOURCES_NOT_RELATED generation. Record VidPN handle, topology handle, mode-set handle, source/target IDs and acquisition callback that produced each resource. Before diagnosing ERROR_GRAPHICS_RESOURCES_NOT_RELATED, do not resize, hot-plug, recreate or release the object under examination.
Run the narrow ERROR_GRAPHICS_RESOURCES_NOT_RELATED comparison. acquire every object from one VidPN instance and repeat the rejected operation. During the ERROR_GRAPHICS_RESOURCES_NOT_RELATED comparison, keep every driver, monitor, resource format and unrelated policy unchanged.
Observe the layer after ERROR_GRAPHICS_RESOURCES_NOT_RELATED. For ERROR_GRAPHICS_RESOURCES_NOT_RELATED, if the exact check passes, record the next HRESULT or visible outcome. A different downstream result shows that the ERROR_GRAPHICS_RESOURCES_NOT_RELATED boundary was crossed.
Repeat ERROR_GRAPHICS_RESOURCES_NOT_RELATED through a lifecycle transition. For ERROR_GRAPHICS_RESOURCES_NOT_RELATED, exercise one relevant resize, mode switch, device recreation, hot-plug or session change and confirm that this result 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. For ERROR_GRAPHICS_RESOURCES_NOT_RELATED, 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 ERROR_GRAPHICS_RESOURCES_NOT_RELATED 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 ERROR_GRAPHICS_RESOURCES_NOT_RELATED 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 ERROR_GRAPHICS_RESOURCES_NOT_RELATED; unrelated adapter, monitor and application state remains unchanged.
For ERROR_GRAPHICS_RESOURCES_NOT_RELATED, debug-layer, ETW or driver diagnostics no longer report the rejected VidPN object relationship contract during the same scenario.
The application handles recurrence of ERROR_GRAPHICS_RESOURCES_NOT_RELATED without an unbounded retry loop, leaked resource, duplicate composition target or stale topology handle.

Implementation notes for `ERROR_GRAPHICS_RESOURCES_NOT_RELATED`

For ERROR_GRAPHICS_RESOURCES_NOT_RELATED, log source and target IDs, topology generation, path descriptors, pinned modes, mode-set handles and monitor timing data. When the ERROR_GRAPHICS_RESOURCES_NOT_RELATED 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 ERROR_GRAPHICS_RESOURCES_NOT_RELATED 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 ERROR_GRAPHICS_RESOURCES_NOT_RELATED.
