ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE

Interpret the result in its owning layer: graphics invalid copyprotection type

The useful interpretation of ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE (0xC026234F) starts at the vidpn boundary: the requested copy-protection type is invalid for the present path descriptor. In practical terms, inspect VidPN path copy-protection selection before changing application-wide graphics settings.

Keep VidPN metadata separate from OPM negotiation

The copy-protection field in a present path must be a recognized type; it is not a shortcut for forcing HDCP, ACP or another OPM protection level. Record the connector, content classification, requested path field and the actual OPM capability result. In the A/B test, submit a documented neutral or supported path value and negotiate protection through the protected-output interface separately. This prevents a malformed enum from being misdiagnosed as an HDCP hardware failure.

ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE: VidPN handles and subobjects are generation-bound. For ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE, A monitor hot-plug, docking action, session switch or mode commit can invalidate an otherwise well-formed cached object. For ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE, 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_INVALID_COPYPROTECTION_TYPE`
Object identity	VidPN path copy-protection selection
Rejected boundary	the requested copy-protection type is invalid for the present path descriptor
Decisive capture	protection enum, connector, content type, OPM capability and target mode
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_INVALID_COPYPROTECTION_TYPE, 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_INVALID_COPYPROTECTION_TYPE.

Reproduce one variable at a time

Freeze the ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE generation. Record protection enum, connector, content type, OPM capability and target mode. Before diagnosing ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE, do not resize, hot-plug, recreate or release the object under examination.
Run the narrow ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE comparison. remove the invalid type or select one reported for the output. During the ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE comparison, keep every driver, monitor, resource format and unrelated policy unchanged.
Observe the layer after ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE. For ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE, if the exact check passes, record the next HRESULT or visible outcome. A different downstream result shows that the ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE boundary was crossed.
Repeat ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE through a lifecycle transition. For ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE, 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_OPM_NOT_SUPPORTED is especially useful: ERROR_GRAPHICS_OPM_NOT_SUPPORTED indicates the output protection subsystem is unavailable. For ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE, recording both names prevents a broad “graphics error” label from merging distinct ownership, capability and lifetime problems.

Recovery contract

Negotiate output protection through OPM and keep VidPN metadata within documented enums. Repair of ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE 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_INVALID_COPYPROTECTION_TYPE 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_INVALID_COPYPROTECTION_TYPE; unrelated adapter, monitor and application state remains unchanged.
For ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE, debug-layer, ETW or driver diagnostics no longer report the rejected VidPN path copy-protection selection contract during the same scenario.
The application handles recurrence of ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE without an unbounded retry loop, leaked resource, duplicate composition target or stale topology handle.

Implementation notes for `ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE`

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