ERROR_GRAPHICS_INVALID_PATH_CONTENT_GEOMETRY_TRANSFORMATION
Interpret the result in its owning layer: graphics invalid path content geometry transformation
The useful interpretation of ERROR_GRAPHICS_INVALID_PATH_CONTENT_GEOMETRY_TRANSFORMATION (0xC0262345) starts at the vidpn boundary: the geometry transformation contains an invalid enum or internally inconsistent combination. In practical terms, inspect present-path scaling or rotation descriptor before changing application-wide graphics settings.
Inspect scaling and rotation as one tuple
The path transformation contains separate scaling and rotation fields whose combination must remain internally valid. Record source dimensions, target dimensions, rotation, scaling, offset and the support bitfields returned during cofunctional modality enumeration. Test identity scaling with zero rotation first, then add one transformation. This sequence distinguishes malformed structure data from a later capability rejection for a valid but unsupported transformation.
Capture before recreating objects
| Capture item | Why it matters |
|---|---|
| What to capture | scaling, rotation, path support flags, source and target modes and pinned state |
| 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 | present-path scaling or rotation descriptor |
| Rejected condition | the geometry transformation contains an invalid enum or internally inconsistent combination |
Reproduce one variable at a time
- Capture the failing state. Record scaling, rotation, path support flags, source and target modes and pinned state.
- Use an enumerated identity transformation and then add one requested transformation.
The comparison with ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_SUPPORTED is especially useful: ERROR_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_SUPPORTED uses a valid transformation the hardware cannot implement.
Recovery contract
Validate scaling and rotation against the path support structure.
- debug-layer, ETW or driver diagnostics no longer report the rejected present-path scaling or rotation descriptor contract during the same scenario.
Implementation notes
Log source and target IDs, topology generation, path descriptors, pinned modes, mode-set handles and monitor timing data.
A production fallback 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.
