commit 9cabb12f746f87d06fabce234edbe17180127034 Author: Lynne <[email protected]> AuthorDate: Tue May 26 11:33:53 2026 +0900 Commit: Lynne <[email protected]> CommitDate: Tue May 26 17:47:04 2026 +0900 vulkan/ffv1_enc_rct_search: write slice_rct_coef directly by main invoc The issue is that SliceContext was passed as an inout, which caused all invocs to locally copy and modify it. When the main invoc wrote it, only the very last written value was used, choosing the wrong coeffs.
