ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED

VidPN path has no pinned content-geometry transformation

ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED is HRESULT 2499409 (0x00262351) from winerror.h. AllStat describes it as “Specified content transformation is not pinned on the specified VidPN present path.” In the Windows display topology or Desktop Window Manager operation, the value reports a nonfailure state that must not be collapsed into plain S_OK.

For ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED, a cleared severity bit does not make the return equivalent to ordinary completion; the postcondition remains specific.

What must be true before accepting it

Verify that the transformation may remain unpinned at the current negotiation phase and callers requiring scaling or rotation wait for commitment. For ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED, that proof prevents usable partial state from being confused with full completion.

For ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED, also confirm that returned outputs belong to the current operation generation and were not inherited from an earlier attempt.

Where the status is encountered

  • ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED can appear during VidPN mode-set, topology, and path negotiation; capture the exact API, object, and phase because the same numeric success severity does not define the state by itself.
  • ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED can appear during display miniport and graphics-kernel dataset enumeration; capture the exact API, object, and phase because the same numeric success severity does not define the state by itself.
  • ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED can appear during DWM composition and GDI redirection-surface handling; capture the exact API, object, and phase because the same numeric success severity does not define the state by itself.

Keep ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED attached to the operation that returned it. Interpreting ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED outside that API contract can turn a normal continuation or partial result into an incorrect retry or false completion.

Diagnostic sequence

  • Capture raw 0x00262351 and ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED before exceptions, signed formatting, or a generic success wrapper removes the symbolic value.
  • Identify the interface, method, callback, service, driver, or broker that returned ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED, including component version, process, thread, and correlation ID.
  • Prove the decisive condition for ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED: the transformation may remain unpinned at the current negotiation phase and callers requiring scaling or rotation wait for commitment.
  • For ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED, inspect every output, count, object handle, callback, queue entry, media item, report, transaction, topology element, or signaling response the call produced.
  • Compare state immediately before and after ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED and verify that ownership, lifetime, persistence, and user-visible effects match the status.
  • Reproduce ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED with the smallest input, then change only the suspected cause and confirm that the return value or postcondition changes as predicted.

Evidence and telemetry

  • Preserve VidPN path ID for ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED.
  • Preserve source and target IDs for ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED.
  • Preserve supported transformations for ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED.
  • Preserve current scaling and rotation policy for ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED.
  • Preserve pin result for ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED.

For ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED, also record UTC time, process and thread IDs, component version, operation generation, and a correlation ID. Keep sensitive ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED content out of logs; use lengths, hashes, GUIDs, and policy-safe metadata where possible.

Correct handling and recovery

Inspect supported transformations and pin one through the documented topology workflow before programming hardware.

A new attempt following ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED should be triggered by a meaningful transition, not merely by elapsed time.

Practical scenario

A display path is created before scaling policy is selected. The driver enumerates supported transformations and waits for the OS to pin one.

A regression test should reproduce ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED, assert all relevant outputs and state, then change only the decisive condition and verify ordinary completion or the expected neighboring result.

Difference from nearby results

This is about path geometry transformation, not source or target display mode pinning.

The distinction around ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED should be visible in control flow, telemetry classification, and user messaging.

Developer and administrator guidance

When ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED crosses COM, RPC, managed, scripting, driver, or service boundaries, preserve the unsigned 32-bit value. Unit tests for ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED should assert the code-specific postcondition, not only success severity.

For ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED, the smallest targeted state change best verifies that the diagnosed condition was causal. Document who owns continuation, cancellation, cleanup, fallback, and user messaging for ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_PINNED.
