ERROR_GRAPHICS_VIDPN_SOURCE_IN_USE
What Windows rejected: graphics vidpn source in use
ERROR_GRAPHICS_VIDPN_SOURCE_IN_USE, value 0xC0262342, is produced by vidpn when another display-mode-management client already owns the source. The investigation should stay attached to DMM client ownership of a VidPN source and to the exact generation in which it was obtained.
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.
Build a useful diagnostic record
| Capture item | Why it matters |
|---|---|
| Supporting trace | source and target IDs, topology generation, path descriptors, pinned modes, mode-set handles and monitor timing data |
| Object identity | DMM client ownership of a VidPN source |
| Rejected condition | another display-mode-management client already owns the source |
| What to capture | source ID, owning DMM client, full-screen state, output mapping and acquisition/release timestamps |
| Current graph state | VidPN, topology, source and target mode sets, and the present path connecting them |
Separate state from capability
- Release the competing owner and retry without changing the topology.
The comparison with DXGI_STATUS_GRAPHICS_VIDPN_SOURCE_IN_USE is especially useful: DXGI_STATUS_GRAPHICS_VIDPN_SOURCE_IN_USE is presentation feedback at the swap-chain layer.
Verify the repaired path
Serialize source ownership and release it on every transition and failure path.
- debug-layer, ETW or driver diagnostics no longer report the rejected DMM client ownership of a VidPN source contract during the same scenario.
