[PATCH v5 0/2] MR9514: gdi32: Fix font creation with invaild bits.
by Bernhard Kölbl March 4, 2026

March 4, 2026

Black Squad's launcher creates a font like ```c font = CreateFontW(12, 0, 0, 0, 0, 0, 0, 0, DEFAULT_CHARSET, 0, 0, 0, 0x80 /* ??? */ | FF_ROMAN, L""); ``` This confuses Wine and causes it to pick a sans serif font instead of a serif one. -- v5: win32u: Mask highest font family bit to zero. https://gitlab.winehq.org/wine/wine/-/merge_requests/9514

[PATCH v12 0/3] MR9874: wineandroid.drv: experimental bring-up fixes for Android 7.1.x
by Twaik Yont (＠twaik) March 4, 2026

March 4, 2026

Requires !10067, fixup/followup to e0d3683d8947cd9a3cb20acdf69091b183a90861 and 4b5311c7e02aa7ab2409f8fdcd22233f116dc4bc. #### Note on authorship and language This text was translated into English and structured with the assistance of ChatGPT. The author is not a native English speaker and may struggle with written technical English; any wording issues are unintentional. #### Description This merge request is an experimental attempt to bring wineandroid.drv back to a minimally functional state on Android 7.1.x. The current Android support appears to have bit-rotted over time, likely due to a combination of internal contract changes in Wine, toolchain and NDK evolution, and the absence of continuous Android testing. The changes proposed here aim to re-establish a working baseline and make the regressions more concrete and easier to reason about. #### Test environment and context All testing so far was performed on Android 7.1.2 x86 images from the Android-x86 project, published on osboxes.org ([link](https://www.osboxes.org/android-x86/)) The primary target is i386 Wine running on x86 Android userspace. Because no up-to-date official Android build scripts were available, Wine was built using Termux as an unsupported but convenient environment for rapid testing. The Java part (WineActivity and related glue code) was built with `sharedUserId = com.termux` purely for convenience (filesystem access and faster prototyping). **Termux is explicitly not considered a supported environment and is mentioned only to provide context for the testing setup.** The build uses Android NDK r29. Since the last known functional Android Wine builds, the NDK and linker behavior have changed multiple times, including symbol visibility and relocation handling. These changes appear to have directly affected several failure modes described below. There is also a known issue with wine-preloader producing excessively large binaries under recent toolchains; a workaround exists but is not included here and is mentioned only as additional context. #### Scope of changes This merge request currently modifies only Android-specific code: - `wineandroid.drv` (native code and Java glue, including WineActivity) - android-only paths in `dlls/ntdll/unix/loader.c` No non-Android platforms are affected. #### Summary of resolved issues 1) Desktop initialization ordering regression After recent `CreateDesktopW`-related changes, `ANDROID_CreateDesktop` started running before the DESKTOP window was created. The Java glue assumed the opposite order. The fix splits desktop initialization into two phases (view setup first, desktop window attachment later via an explicit is_desktop flag) and corrects the `ANDROID_CreateDesktop` success return value. 2) Rendering stalls and `USER lock assertion` Occasional crashes with: ``` err:system:user_check_not_lock BUG: holding USER lock ``` A full memory barrier was added in the dequeue path to avoid a likely memory ordering issue. Additionally, a guard was added for a `NULL` buffer returned on successful dequeue. 3) Early startup failure in `virtual_alloc_first_teb` Wine frequently failed with: ``` err:virtual:virtual_alloc_first_teb wine: failed to map the shared user data: c0000018 ``` `virtual_init()` is now called from `JNI_OnLoad()` to reduce the likelihood of the JVM reserving the required address range before Wine initializes its virtual memory subsystem. #### Remaining issues - Window focus handling is partially broken: windows receive focus on click, but are not always raised to the front. - Despite the available desktop area being larger (e.g. 1024x696), Wine consistently reports a display resolution of 800x600. #### Limitations Wine on Android stopped functioning entirely starting with Android 8. As a result, all testing so far has been limited to Android 7.1.x. No claims are made about behavior on newer Android versions. #### Out of scope This merge request intentionally does not attempt to: - redesign IPC mechanisms - introduce new Android integration models - address Android 8+ compatibility The sole goal is to re-establish a minimally working baseline on Android 7.1.x and enable informed discussion about what regressed and how to proceed. **This is my first contribution to Wine, and I am aware that some parts of this analysis or implementation may be flawed. I would be grateful for any review comments or suggestions.** <details> <summary>Also, the screenshot of the working prototype.</summary> ![1](/uploads/666d78a712edce531a25521a2615ea9f/1.png){width=756 height=600} </details> -- v12: ntdll: call virtual_init from JNI_OnLoad to avoid early virtual_alloc_first_teb failure Wineandroid: Sanitize dequeueBuffer result and reject missing buffers. wineandroid: fix desktop init ordering after CreateDesktopW changes https://gitlab.winehq.org/wine/wine/-/merge_requests/9874

[PATCH v2 0/1] MR10201: dwrite: Add locales to locale list.
by Daniel Lehman (＠dlehman25) March 4, 2026

March 4, 2026

The Chinese version of the Noto Sans CJK font was being chosen despite being in Japanese locale. Specifically, Noto Sans CJK SC was used for 0x5c06 instead of Noto Sans CJK JP. The locale list for the system fallback collection was just the neutral locale. -- v2: dwrite: Add locales to locale list. https://gitlab.winehq.org/wine/wine/-/merge_requests/10201

[PATCH v7 0/3] MR9874: wineandroid.drv: experimental bring-up fixes for Android 7.1.x
by Twaik Yont (＠twaik) March 4, 2026

March 4, 2026

Requires #10067, fixup/followup to e0d3683d8947cd9a3cb20acdf69091b183a90861 and 4b5311c7e02aa7ab2409f8fdcd22233f116dc4bc. #### Note on authorship and language This text was translated into English and structured with the assistance of ChatGPT. The author is not a native English speaker and may struggle with written technical English; any wording issues are unintentional. #### Description This merge request is an experimental attempt to bring wineandroid.drv back to a minimally functional state on Android 7.1.x. The current Android support appears to have bit-rotted over time, likely due to a combination of internal contract changes in Wine, toolchain and NDK evolution, and the absence of continuous Android testing. The changes proposed here aim to re-establish a working baseline and make the regressions more concrete and easier to reason about. #### Test environment and context All testing so far was performed on Android 7.1.2 x86 images from the Android-x86 project, published on osboxes.org ([link](https://www.osboxes.org/android-x86/)) The primary target is i386 Wine running on x86 Android userspace. Because no up-to-date official Android build scripts were available, Wine was built using Termux as an unsupported but convenient environment for rapid testing. The Java part (WineActivity and related glue code) was built with `sharedUserId = com.termux` purely for convenience (filesystem access and faster prototyping). **Termux is explicitly not considered a supported environment and is mentioned only to provide context for the testing setup.** The build uses Android NDK r29. Since the last known functional Android Wine builds, the NDK and linker behavior have changed multiple times, including symbol visibility and relocation handling. These changes appear to have directly affected several failure modes described below. There is also a known issue with wine-preloader producing excessively large binaries under recent toolchains; a workaround exists but is not included here and is mentioned only as additional context. #### Scope of changes This merge request currently modifies only Android-specific code: - `wineandroid.drv` (native code and Java glue, including WineActivity) - android-only paths in `dlls/ntdll/unix/loader.c` No non-Android platforms are affected. #### Summary of resolved issues 1) Desktop initialization ordering regression After recent `CreateDesktopW`-related changes, `ANDROID_CreateDesktop` started running before the DESKTOP window was created. The Java glue assumed the opposite order. The fix splits desktop initialization into two phases (view setup first, desktop window attachment later via an explicit is_desktop flag) and corrects the `ANDROID_CreateDesktop` success return value. 2) Rendering stalls and `USER lock assertion` Occasional crashes with: ``` err:system:user_check_not_lock BUG: holding USER lock ``` A full memory barrier was added in the dequeue path to avoid a likely memory ordering issue. Additionally, a guard was added for a `NULL` buffer returned on successful dequeue. 3) Early startup failure in `virtual_alloc_first_teb` Wine frequently failed with: ``` err:virtual:virtual_alloc_first_teb wine: failed to map the shared user data: c0000018 ``` `virtual_init()` is now called from `JNI_OnLoad()` to reduce the likelihood of the JVM reserving the required address range before Wine initializes its virtual memory subsystem. #### Remaining issues - Window focus handling is partially broken: windows receive focus on click, but are not always raised to the front. - Despite the available desktop area being larger (e.g. 1024x696), Wine consistently reports a display resolution of 800x600. #### Limitations Wine on Android stopped functioning entirely starting with Android 8.

[PATCH v5 0/2] MR9997: shell32: ShellExecute uses SW_SHOWDEFAULT by default
by Fan Zhou (＠zhoufan_uniontech) March 4, 2026

March 4, 2026

This patch applies to applications that launch processes via ShellDispatch specified as VT_EMPTY type (such as WPS PDF Editor).\ It prevents the conversion of VT_EMPTY type to the INT_4 value of 0 (i.e., SW_HIDE), which would otherwise cause the main program window not to be displayed. -- v5: shell32: ShellExecute uses SW_SHOWDEFAULT by default https://gitlab.winehq.org/wine/wine/-/merge_requests/9997

[PATCH v10 0/1] MR10193: dlls/comdlg32：Add the implementation of IServiceProvider_fnQueryService to obtain IFolderView2
by pan hui (＠panhui) March 4, 2026

March 4, 2026

An application adds a new button using IFileDialogCustomize_AddPushButton. The application obtains IServiceProvider_iface through QueryInterface using the parameter IFileDialogCustomize_iface of the callback function IFileDialogControlEvents_OnButtonClicked, and then uses IServiceProvider_iface to pass IID_IFolderView and IID_IFolderView2 through IServiceProvider_fnQueryService to obtain IFolderView2. After that, it obtains the selected files and folders through IFolderView2_GetSelection. Currently, the implementation of obtaining IFolderView2 through IServiceProvider_fnQueryService is missing and needs to be added. -- v10: dlls/comdlg32：Add the implementation of IServiceProvider_fnQueryService to obtain IFolderView2 https://gitlab.winehq.org/wine/wine/-/merge_requests/10193
