STATUS_GRAPHICS_PATH_CONTENT_GEOMETRY_TRANSFORMATION_NOT_SUPPORTED
The requested transformation is valid but not supported by the path
This status is returned after the transformation value is understood, but the driver or hardware cannot support it on the specified source-target path. Rotation, scaling, or related content-geometry handling can be constrained by target mode, primary-surface layout, scan-out engine, or path capabilities.
The distinction from an invalid transformation is important. The caller may be able to choose another transformation or mode, while a malformed value points to a bug in parameter construction. Capability logging should therefore include the path and mode combination.
What to check
- Record source mode, target mode, rotation or transformation, and path capabilities together.
- Try a supported transformation only after confirming that the current value is valid but unsupported.
- Check optimized rotation requirements for WDDM 1.2+ drivers when rotation is involved.
