[PATCH 0/2] MR10809: comctl32: Fix VARHEIGHT rebar scaling when cyIntegral == 0
by Feli Rippmann (＠Feli) May 3, 2026

May 3, 2026

This is a test and fix for an edge case in the rebar component where `cyChild` is set to a larger value than `cyMaxChild` while `cyIntegral` is exactly 0 on a VARIABLEHEIGHT rebar. On Windows, at least the two Win11 machines I have acces to, the WinAPI seems to clamp the value to `cyMaxChild` so the test passes. On Wine, it does not clamp the value and the test fails, but passes with the fix. Specifically, Wine's behaviour results in the program EffectsEd3 from the modding tools of Call of Duty: World at War sizing its rebar height incorrectly, taking over the whole window and making the program unusable. With the fix, this is no longer the case and the program becomes usable. ![EffectsEd3 before Patch.png](/uploads/496a3bfe57dd15fb7e98c9a18073f5fb/EffectsEd3_before_Patch.png){width=255 height=189} - ![EffectsEd3 after Patch.png](/uploads/f57ac713c373b3063142f4e45b209a93/EffectsEd3_after_Patch.png){width=351 height=185} -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10809

[PATCH v14 0/9] MR10569: wineandroid: rework Android integration and switch to split process model
by Twaik Yont (＠twaik) May 2, 2026

May 2, 2026

This series reworks the wineandroid driver and moves it away from the current “Wine inside JVM process” model to a split architecture where the Android activity (UI) and Wine run in separate processes. The existing model relies on running Wine inside the JVM process and interacting with Android through JNI callbacks and APC/unixlib-based dispatch. This approach no longer works reliably on modern Android: - Android 10+ applies seccomp restrictions to app processes, making a number of required syscalls unavailable inside the activity process, while processes started via fork/exec are not subject to the same limitations. - The implementation depends on Wine thread context (TEB), signal handling, and register state assumptions that conflict with the JVM runtime (e.g. segment register usage on x86), requiring fragile workarounds. - Due to sandboxing, it is difficult to reliably debug or even observe all failure modes, and future Android changes are likely to tighten these restrictions further. At the same time, downstream projects such as MiceWine, Winlator, Termux’s Wine environment, GameHub and GameNative already use a model where the UI (activity) and Wine run in separate processes and communicate via IPC, which has proven to work reliably on current Android systems. This series implements that model in wineandroid: - Wine is now started in a separate process via fork/exec instead of running inside the JVM process. - Android-facing code no longer depends on the Wine APC/unixlib execution path and runs on the UI thread where appropriate (e.g. native window registration). - ioctl handling is reworked to remove reliance on Wine thread context, with explicit JNIEnv usage and fd-based reply plumbing. - Environment setup and initialization are moved to the Java side, simplifying the native startup path. - Logging for ioctl paths is routed through Android logcat without depending on a Wine TEB. The changes are split into multiple bisect-safe commits to keep intermediate states functional while migrating the code step by step. With Wine running in a separate process, it is no longer subject to JVM seccomp restrictions, and there are no longer conflicts between JVM and Wine execution contexts (signals, thread state, register usage, etc.). <details> <summary>Old message</summary> wineandroid: move ioctl handling to dedicated Java-only thread Move ioctl handling out of the Wine APC/unixlib execution path into a dedicated Java-only thread without Wine context. On Android 10+ a number of syscalls are restricted inside the activity process via seccomp, while processes started via fork/exec are not subject to the same limitations. Decoupling ioctl handling from the Wine context is required to eventually run this code outside of the activity process. This change introduces a new transport and execution model where ioctl dispatch no longer depends on Wine thread state, preparing for moving the Android backend into a separate process. The refactor is intentionally split into multiple bisect-safe commits to keep intermediate states functional while gradually migrating the dispatch path. Since this is a fairly large chunk of work, I’d like to make sure we’re aligned before continuing. </details> -- v14: wineandroid: split Android driver and Wine into separate processes wineandroid: terminate activity when desktop client disconnects wineandroid: make JNI initialization work with direct JVM loading wineandroid: create desktop view via ioctl and pass event pipe wineandroid: return ioctl errors directly wineandroid: remove unixlib/ntoskrnl ioctl path wineandroid: switch dequeueBuffer to socket transport wineandroid: switch ioctl dispatch to socket transport on main thread looper wineandroid: add reply_fd plumbing to ioctl path https://gitlab.winehq.org/wine/wine/-/merge_requests/10569

[PATCH 0/1] MR10805: Draft: msvcrt: only convert _tolower_l if not exact match already
by Stephan Seitz (＠theHamsta) May 2, 2026

This optimizations brought some speed-ups in https://gitlab.winehq.org/wine/wine/-/merge_requests/10804 for the equivalent `memicmp_strW` function as it avoids converting and locale lookup for exact matches. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10805
