[PATCH 0/1] MR9077: imm32: ensure HIMC is unlocked in ImmGenerateMessage
by zhengyong chen (＠chenzhengyong) 30 Sep '25

30 Sep '25

Previously, ImmGenerateMessage could return early when ImmLockIMCC(ctx-\>hMsgBuf) failed, without unlocking the HIMC obtained via ImmLockIMC. This could leave the HIMC locked and lead to resource leaks. This patch adds calls to ImmUnlockIMC(himc) at all early return points, and also unlocks the HIMC before returning TRUE at the end, ensuring that every ImmLockIMC call is properly balanced with a corresponding ImmUnlockIMC. Tested on: Ubuntu 25.10 & deepin Linux V25, Wine compiled from master branch. No functional behavior of message dispatch is changed.

[PATCH 0/2] MR9014: server: Create an inproc sync for user APC signaling.
by Rémi Bernon (＠rbernon) 30 Sep '25

30 Sep '25

Unlike the message queue for which I believe we can get rid of any special handling, I don't see a way to avoid a dedicated inproc sync for user APCs. This will make sure that the sync gets created on thread creation. It could arguably be lazily allocated instead, but I don't see a reason to delay the failure to a later time and end up with successfully created but unalertable thread when they are supposed to be. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9014

[PATCH v2 0/1] MR9052: win32u: Handle errors when creating EGL context
by Vasiliy Stelmachenok (＠ventureoo) 30 Sep '25

30 Sep '25

Some background: I wanted to test EGL backend on my old laptop with Intel graphics limited with OpenGL 2.1 / GLES 2.0. When trying to run any game this led to a crash with NULL GL_RENDERER, but not with GLX. Tracing has shown that wined3d tries to create a context with high `WGL_CONTEXT_MAJOR_VERSION_ARB`/`WGL_CONTEXT_MINOR_VERSION`, which is not supported by hardware, resulting in the creation of nil context in EGL, but due to lack of error handling it's always assumed to be successful. In GLX this results in an error and creating a context does not lead to success, after which it tries again to create a context with a lower `WGL_CONTEXT_MAJOR_VERSION_ARB` / `WGL_CONTEXT_MINOR_VERSION` until the actual context is created. Proper error handling when creating EGL context as in this patch also allows wined3d to work on such hardware. -- v2: win32u: Handle errors when creating EGL context https://gitlab.winehq.org/wine/wine/-/merge_requests/9052
