[PATCH v4 0/30] MR2122: Draft: winex11: Support fixed X11 keycode to scancode conversion.
by Rémi Bernon June 2, 2026

June 2, 2026

X11 keycodes are just Linux keycodes + 8 nowadays according to evdev or libinput drivers, and we can avoid innacurate reconstruction in the most common case. Opening this as a draft for now, to show where I'd like to go with https://gitlab.winehq.org/wine/wine/-/merge_requests/2062. -- v4: winex11: Use KbdLayerDescriptor for ToUnicodeEx. win32u: Force US layout in ToUnicode when CTRL is pressed. winex11: Use KbdLayerDescriptor for VkKeyScanEx. winex11: Use KbdLayerDescriptor for MAPVK_VK_TO_CHAR. winex11: Fill the Xkb layout KBDTABLES VkToWchar tables. winex11: Use KbdLayerDescriptor for GetKeyNameText. winex11: Fill the Xkb layout KBDTABLES KeyNames tables. winex11: Use KbdLayerDescriptor for MapVirtualKeyEx. winex11: Create KBDTABLES with VSCtoVK tables for Xkb layouts. winex11: Lookup xkb layout in KbdLayerDescriptor. win32u: Introduce KbdLayerDescriptor user driver entry. winex11: Get rid of now unnecessary EVENT_event_to_vkey. server: Convert CTRL + VK_PAUSE to VK_CANCEL. winex11: Drop now unnecessray nonchar_key_vkey table. winex11: Drop now unnecessary keyboard layout detection code. winex11: Use static scan code to vkey mapping tables. winex11: Support fixed X11 keycode to scancode conversion. winex11: Use scancode high bit to set KEYEVENTF_EXTENDEDKEY flag. winex11: Don't update the keyboard layouts on MappingNotify. winex11: Stop sending WM_INPUTLANGCHANGEREQUEST on MappingNotify. winex11: Send WM_INPUTLANGCHANGEREQUEST when Xkb group changes. crypt32: Avoid using uninitialized memory. winex11: Compute Xkb keyboard layout ID and language. winex11: Keep a list of every known Xkb keyboard layout. winex11: Read the _XKB_RULES_NAMES root window property. winex11: Listen to _XKB_RULES_NAMES root window property changes. win32u: Avoid accessing NULL key name string pointer. win32u: Init vsc2char in NtUserMapVirtualKeyEx only if necessary. win32u: Init vsc2vk in NtUserMapVirtualKeyEx only if necessary. win32u: Init vsc2vk in NtUserGetKeyNameText only if necessary.

[PATCH v6 0/12] MR10058: Draft: ntdll: Spawn main thread as a separate thread.
by Rémi Bernon June 2, 2026

June 2, 2026

This makes sure macOS main thread is a Wine thread as in https://gitlab.winehq.org/wine/wine/-/merge_requests/9579, while keeping its event loop usable for GUI, and makes every other platform work the same. Their main thread is parked for now, but the idea is to use the poll loop for various unix side internal purposes, such as winewayland pipe polling, compositing, etc. On macOS the main loop would be used similarly. -- v6: ntdll: Use CFRunLoopRun to implement sched_run on macOS. ntdll: Dont allocate a user stack for the unix main thread. ntdll: Spawn the application main thread as a separate thread. server: Initialize process tracing in get_startup_info. ntdll: Send process PEB / initial TEB in get_startup_info. ntdll: Call get_startup_info request even when it is empty. ntdll: Pass the startup info size to init_startup_info. server: Create the new process first thread in new_process request. server: Return new process thread handle from get_new_process_info. ntdll: Pass thread security descriptor to new_process request. ntdll: Pass the main thread flags in the new_process request. server: Pass a thread flags parameter to create_thread. https://gitlab.winehq.org/wine/wine/-/merge_requests/10058

[PATCH v12 0/8] MR10019: opengl32: Move wglGetProcAddress implementation to the PE side.
by Rémi Bernon June 2, 2026

June 2, 2026

This better splits client / host extension lists, allowing to more easily check for available host-side extensions in win32u later on, then moves the function registry to the PE side to get rid of the remaining extension logic in opengl32 unix side. Doing that, it also drops the driver function check, and always expose extension functions to the client if their extension dependency is satisfied. I'm not completely sure this is right, but I think the unix side tends to expose functions from eglGetProcAddress more often than the opposite. We could also keep a mechanism to check the driver availability, with a bit of additional complexity. On the unix side, all OpenGL functions are queried on initialization instead of just core functions, simplifying their use later on. -- v12: opengl32: Implement the function registry on the PE side. win32u: Query every OpenGL functions on initialization. opengl32: Implement client extension enumeration on the PE side. opengl32: Move major / minor version to the PE side context wrapper. opengl32: Parse host extension list to the opengl_extensions struct. opengl32: Remove now unused wgl pixel format unix thunks. opengl32: Implement wglGetExtensionsString(ARB|EXT) on the PE side. opengl32: Initialize enabled / disabled OpenGL extensions struct. https://gitlab.winehq.org/wine/wine/-/merge_requests/10019

[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 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
