[PATCH v6 0/3] MR9777: mfplat: Implement mf d3d12 synchronization object.
by Charlotte Pabst (＠CharlottePabst) June 1, 2026

June 1, 2026

I'm also working on tests & implementation for d3d12-backed IMFMediaBuffers and sample allocators, submitting this here to receive some feedback while working on more. Sorry if the tests are too involved, perhaps they could be simplified, but since there is very little documentation on this I had to figure out a lot of minor details using tests. The use case is Fuga Melodies of Steel 3 which uses the UE5 electra decoder plugin. It expects d3d12 support in media foundation (sample allocator, media buffer, sync object). This game doesn't require implementing proper d3d12 video decoding, only that frame data is stored in a IMFMediaBuffer that is backed by a ID3D12Resource. Once finished, this feature would presumably help with other UE5 games that have similar usage patterns as well (All the code for it is in UE5, which is source-available). Other real world examples are limited, but I believe chromium and mesa have some optional code using this feature. MFCreateD3D12SynchronizationObject is (presumably) used by MFCreateDXGISurfaceBuffer to create a synchronization object for the buffer (I already have some tests that query and use the synchronization object from a d3d12-backed mediabuffer, which I will submit together with the other d3d12 buffer tests.) -- v6: mfplat: Implement mf d3d12 synchronization object. mfplat/tests: Add tests for mf d3d12 synchronization object. https://gitlab.winehq.org/wine/wine/-/merge_requests/9777

[PATCH v2 0/1] MR10916: secur32: Return SEC_E_INVALID_TOKEN for invalid TLS record headers
by Ivan Lyugaev (＠valy) June 1, 2026

June 1, 2026

I encountered an issue with establishing an encrypted connection to the mail server in Outlook. I managed to find out that Outlook tries various connection setup options — in particular, it sends a ClientHello to server port 587, and in response receives an SMTP banner, which in the establish_context function (https://gitlab.winehq.org/wine/wine/-/blame/master/dlls/secur32/schannel.c?…) is mistakenly interpreted as TLS and returns a SEC_E_INCOMPLETE_MESSAGE error. This causes further reading of data from the server → an error and connection break. I managed to fix it by adding validation of the first bytes of the buffer to match the TLS header. -- v2: secur32: Return SEC_E_INVALID_TOKEN for invalid TLS record headers https://gitlab.winehq.org/wine/wine/-/merge_requests/10916

[PATCH 0/1] MR11030: Add support for a layered window region. (v3)
by Ivan Lyugaev (＠valy) June 1, 2026

June 1, 2026

When WindowFromPoint is called with a point inside the transparent region of the top-level window, the top-level window is returned instead of the expected window beneath it. I found that this problem was previously addressed in the patch [https://gitlab.winehq.org/wine/wine-staging/-/blob/master/patches/user32-Mo…] I adapted that patch for the current version and added a test. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/11030

[PATCH v6 0/4] MR10960: scrrun/dictionary: Match native semantics for Empty and Boolean keys.
by Francis De Brabandere (＠francisdb) June 1, 2026

June 1, 2026

An uninitialized VBScript variable is Empty, so scripts can end up using Empty as a dictionary key alongside a numeric 0 or "". Native treats those as the same key; Wine kept Empty distinct from every other type. Match an Empty key against any numeric zero or the empty string, while keeping it distinct from Null and from non-zero/non-empty keys. A Boolean key was rejected outright (E_NOTIMPL), breaking Exists/Remove when a script uses a comparison result as a key; hash it by its numeric value like the other numeric types. -- v6: scrrun/dictionary: Match native key semantics for Boolean keys. scrrun/tests: Add tests for Boolean dictionary keys. scrrun/dictionary: Match Empty keys against zero-valued and empty-string keys. scrrun/tests: Add tests for Empty dictionary keys. https://gitlab.winehq.org/wine/wine/-/merge_requests/10960

[PATCH v28 0/6] MR10515: vbscript: Bind local variables, class properties, and loop variables at compile time.
by Francis De Brabandere (＠francisdb) June 1, 2026

June 1, 2026

Resolve identifiers to direct indices during compilation instead of doing runtime `wcsicmp` string scans in `lookup_identifier()`. This adds new opcodes that access local variables, function arguments, class properties, and loop variables by index, eliminating the linear string comparison overhead for the most common cases. **New opcodes:** - `OP_local` / `OP_assign_local` / `OP_set_local` - read/write local vars and args by index - `OP_local_prop` / `OP_assign_local_prop` / `OP_set_local_prop` - read/write class properties by index - `OP_step_local` / `OP_incc_local` - For-loop step/increment with indexed counter - `OP_enumnext_local` - For-Each iteration with indexed loop variable This mirrors jscript's `OP_local` / `bind_local()` optimization (`dlls/jscript/compile.c`) and addresses the FIXME in `lookup_identifier()` noting that class property access should be bound at compile time. Names that cannot be resolved at compile time (globals in Execute/ExecuteGlobal code, dynamic vars, host objects) continue to use the existing string-based path. Patched against Wine master (0c0d2643), measured on two real-world VBScripts (75K-line / 89-class and 37K-line / 17-class), 5 runs each: - Script A (loop/local-heavy): steady-state simulation -7.73 %, full run -4.63 %, top per-timer cumulative wall -6.18 % - Script B (class-method-heavy): steady-state -3.97 %, full run -4.18 %, top per-timer -3.13 % perf confirms the mechanism: lookup_identifier drops 9.52 % → 3.68 % of self-time, with the new interp_local taking 3.30 %. -- v28: vbscript: Bind class properties at compile time. vbscript: Bind For-loop variables at compile time. vbscript: Factor out do_for_step and do_incc from interp_step and interp_incc. vbscript: Bind local variable assignments at compile time. vbscript: Factor out assign_local_var from assign_ident. vbscript: Bind local variables and arguments at compile time. https://gitlab.winehq.org/wine/wine/-/merge_requests/10515

[PATCH v11 0/3] MR10897: vbscript: Handle declaration scope in the parser.
by Francis De Brabandere (＠francisdb) June 1, 2026

June 1, 2026

ClassDeclaration was only accepted at the top SourceElement level, so a prior statement on the same line (e.g. Dim x : Class C) failed to parse instead of being accepted or, for a name collision, reported as err 1041. Make ClassDeclaration a SimpleStatement and register it as a class at compile time in source order. Sub, Function and Class declarations are only valid at script global scope. A global If/ElseIf/Else/Select block still hoists a Sub or Function to global scope, but a loop (For/For Each/While/Do) or With block does not, and a Class is never hoisted. Reject the disallowed cases during parsing, reporting the location native reports rather than failing later during bytecode emission. -- v11: vbscript/tests: Add tests for sub declaration scope. vbscript: Handle class declaration scope in the parser. vbscript/tests: Add tests for class declaration scope. https://gitlab.winehq.org/wine/wine/-/merge_requests/10897
