ERROR_GRAPHICS_UNSWIZZLING_APERTURE_UNSUPPORTED

ERROR_GRAPHICS_UNSWIZZLING_APERTURE_UNSUPPORTED (0xC0262108) means the selected allocation does not support unswizzling through an aperture. The requested operation is incompatible with the allocation layout or backing segment.

What to check

  • Use a resource type and memory layout supported by the operation instead of forcing the existing allocation through an unsupported path.
  • For driver development, inspect the allocation flags, segment placement, and format assumptions.
  • For application failures, keep the driver and application versions together in the incident data because the issue is implementation-specific.
