Use an explicit placed buffer for software frame copies so the D3D copy uses the same row pitch published through KVMFR. GetCopyableFootprints describes buffer copies and cannot be used to infer the physical layout of a placed row-major texture. This caused padded resolutions to use the wrong row starts in every consumer. Keep the copy direct to IVSHMEM without a staging or CPU copy.
