What Windows rejected: graphics path content geometry transformation not supported
ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_SUPPORTED, value 0xC0262346, is produced by vidpn when the requested scaling or rotation is structurally valid but unsupported on that source-target path. The investigation should stay attached to path transformation capability and to the exact generation in which it was obtained.
Build a useful diagnostic record
| Capture item | Why it matters |
|---|---|
| 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 |
| Object identity | path transformation capability |
| Rejected condition | the requested scaling or rotation is structurally valid but unsupported on that source-target path |
| What to capture | requested transformation, driver-reported support flags, source/target modes and connector |
Separate state from capability
- Select identity or another advertised transformation while keeping modes fixed.
The comparison with ERROR_GRAPHICS_INVALID_PATH_CONTENT_GEOMETRY_TRANSFORMATION is especially useful: ERROR_GRAPHICS_INVALID_PATH_CONTENT_GEOMETRY_TRANSFORMATION rejects malformed transformation data.
Verify the repaired path
Offer only transformations returned by cofunctional modality enumeration.
- debug-layer, ETW or driver diagnostics no longer report the rejected path transformation capability contract during the same scenario.
