[PATCH 0/1] MR10338: comctl32/tooltips: Prevent tooltip from reappearing immediately after a click.
by Ivan Georgiev (＠ivanresen2006) April 27, 2026

April 27, 2026

When a mouse button is clicked while hovering over a tool, Windows hides the tooltip and suppresses it from reappearing until the cursor leaves the tool and re-enters it. Previously Wine would restart ID_TIMERSHOW on subsequent mouse moves over the same tool, causing the tooltip to pop up again immediately. Fix this by introducing a bClickCancelled flag that is set whenever any mouse button is pressed over an active tool, and cleared only when the cursor moves to a different tool. Also kill ID_TIMERSHOW in TOOLTIPS_Hide to prevent a pending show timer from firing after the tooltip is dismissed.

[PATCH v3 0/5] MR9777: mfplat: Implement mf d3d12 synchronization object.
by Charlotte Pabst (＠CharlottePabst) April 22, 2026

April 22, 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.) -- v3: mfplat: Use freelist for mfd3d12 syncobj release. mfplat/tests: Test that mfd3d12 syncobj release keeps working through multiple resets. mfplat: Implement mf d3d12 synchronization object. mfplat/tests: Add tests for mf d3d12 synchronization object. mfd3d12.h: Add some missing definitions. https://gitlab.winehq.org/wine/wine/-/merge_requests/9777

[PATCH 0/1] MR10488: win32u: Optimize the speed of halftone primitives by using 32.32 fixed point arithmetic.
by Zhiyi Zhang (＠zhiyi) April 21, 2026

April 21, 2026

Floating-point operations are expensive, especially when running on x86 CPU emulators. Tests show that speed after this commit is improved by 18% on AMD 9950x with no visual difference.

[PATCH 0/1] MR10276: ntdll/wineandroid: Redirect stdout/stderr to Android logcat in the Java startup path
by Twaik Yont (＠twaik) April 19, 2026

April 19, 2026

This change redirects Wine’s `stdout` and `stderr` to Android `logcat` when running through the Java entry point used by `wineandroid.drv`. Currently `WineActivity` writes debug output to a file via the `WINEDEBUGLOG` mechanism. In practice this is inconvenient to use: the file lives in the application's private storage and reading it on a device typically requires either a debug build or root access. Even when accessible, inspecting logs directly on the device is less practical than using Android’s standard logging tools. Android applications normally expose diagnostic output through logcat. This change forwards Wine’s `stdout` and `stderr` to `logcat` so that Wine debug output can be observed using standard Android tooling (`adb logcat`, Android Studio, etc.) without accessing the application’s internal storage. The implementation is intentionally simple and best-effort. A pipe is installed on `stdout` and `stderr` and a small detached thread forwards the output to `__android_log_write()`. Data is forwarded in chunks without reconstructing line boundaries; this is sufficient for diagnostic purposes and keeps the implementation minimal. The redirection is only enabled in the Android Java startup path, which corresponds to the environment used by `wineandroid`. In this configuration `stdout` and `stderr` are typically not visible to the user (commonly pointing to `/dev/null`), so redirecting them to logcat does not replace any usable diagnostics channel. It is also unlikely that Wine will be compiled directly on Android devices in practice. Android does not provide an official NDK toolchain that runs on-device, and mingw toolchains are not distributed for Android either. Building Wine therefore normally happens off-device using standard cross-compilation toolchains (android NDK, mingw, host toolchain). Because of this, the `logcat` forwarding is primarily intended for runtime diagnostics and debugging rather than build-time development directly on the device. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10276

[PATCH v4 0/1] MR8794: shell32: Restore the ability of running unix executables via unix paths
by Yuxuan Shui (＠yshui) April 17, 2026

April 17, 2026

MobaXTerm tries to ShellExecute "/bin/sh" when running under wine. This ability to run unix executables on the host via unix paths was accidentally removed in the attemp to align ShellExecute more closely with native, while fixing the problem that sometimes wrong executable is started by ShellExecute (e.g. in Motor Race Collection).

[PATCH 0/1] MR10498: vbscript: Return correct error codes for missing statement separators.
by Francis De Brabandere (＠francisdb) April 15, 2026

April 15, 2026

When a statement and its closing keyword appear on the same line without a separator (newline or colon), Windows returns specific error codes: - 1042 (Must be first statement on the line) for End If, End Select - 1024 (Expected statement) for End While, End Class, Else End If - 1025 (Expected end of statement) for Wend, Loop Wine was returning generic E_FAIL (16389) for all of these. Add targeted error productions in the parser grammar to detect block-closing keywords following a statement without a separator, and set the appropriate VBScript error code before aborting. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10498

[PATCH 0/2] MR10072: shell32: Always update `outlen` (`pcchOut`) when querying strings
by Marijn Suijten (＠Marijn) April 15, 2026

April 15, 2026

At least `AssocQueryStringW()` is documented to update the character count in `pcchOut` to "the number of characters actually placed in the buffer" which requires us to update the value of `*outlen` even when the buffer size was sufficient: https://learn.microsoft.com/en-us/windows/win32/api/shlwapi/nf-shlwapi-asso… Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=59402 -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10072
