by Ignacy Kuchciński Dec. 30, 2025

Dec. 30, 2025

This fixes the crash when launching ClipStudioPaint.exe with Windows 10 compatiblity mode by adding the minimum required windows.ui and windows.storage definitions and stubs. Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=58254 -- v8: windows.storage: Add stubs for StorageFile class. include: Add Windows.Storage.StorageFile missing definitions. windows.ui: Add stubs for RadialController classes. include: Add Windows.UI.Input.RadialController definitions. https://gitlab.winehq.org/wine/wine/-/merge_requests/8394

[PATCH 0/3] MR9839: dcomp: Create stub implementations for DirectComposition
by Jaakko Hannikainen (＠jgke) Dec. 30, 2025

Dec. 30, 2025

These stub implementations enable Dorico to successfully boot. They don't implement any real rendering or linkings to rendering contexts, they just create various interfaces with methods returning E_NOTIMPL. Notably, the `CompositionDevice` family has some interesting inheritance relations: * `IDCompositionDevice` inherits from `IUnknown` * `IDCompositionDevice2` also inherits from `IUnknown`, rather than `IDCompositionDevice` * `IDCompositionDesktopDevice` and `IDCompositionDevice3` both inherit from `IDCompositionDevice2`, rather than one inheriting from the other This means that a implementation of these needs to provide separate interfaces for at least `IDCompositionDevice` , `IDCompositionDesktopDevice` and `IDCompositionDevice3` . This MR also provides an 'implementation' for `IDCompositionDevice2` . The three commits here are: * Implement bare minimum of the `DCompositionCreateDevice` and `DCompositionCreateDevice2` to get Dorico to boot, ie. return the appropriate interfaces from those functions, which do nothing expect for some additional allocation functions, such as `IDCompositionDevice:CreateTargetForHwnd` . * Implement rest of `DCompositionCreateDevice`, `DCompositionCreateDevice2` and `DCompositionCreateDevice3`, and use shared 1implementations' for all of the related interfaces * Return fake S_OK responses from `IDCompositionDevice:Commit`, `IDCompositionTarget:SetRoot` and `IDCompositionVisual:SetContent` -- Dorico has one tool window where the software actually checks the response codes from all of these, and if any of these return E_NOTIMPL the entire software crashes. These prevent the crash, but the window in question will be rendered completely white. This is my first contribution for Wine, if there's some weird code it's most likely because of me, and not Microsoft. I don't have a bug for Dorico because the installer seems to require half of the internet through winetricks, but I believe this Cubase bug is caused by the same code: https://bugs.winehq.org/show_bug.cgi?id=57680 -- which I couldn't verify because the installers for Cubase currently don't seem work under Wine. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9839

[PATCH v2 0/1] MR9834: user32: Test DlgDirList in a temp directory.
by James Hawkins (＠truiken) Dec. 29, 2025

DlgDirList can fail to enumerate files for the ListBox in some scenarios, e.g., when the current directory is a UNC mount provided by the WSL 2 9P server.

[PATCH 0/1] MR9836: wow64: Only compare the valid segment selector part
by André Zwing Dec. 29, 2025

Dec. 29, 2025

VARA.exe (Visual Basic 6 application) needs this on ARM64, as there can be garbage in the upper words of the segments. The garbage seems to get there through calls to NtRaiseException. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9836

[PATCH v4 0/2] MR9835: Server: Add wrapper for debug and error output
by Ralf Habacker (＠rhabacker) Dec. 29, 2025

Dec. 29, 2025

While working on !7650, it turned out that the logs generated by wineserver do not use a prefix, which makes it difficult to distinguish the corresponding entries in combined logs e.g. `WINEDEBUG=+file,+winsock,+server` from the other debug channels. This is fixed by this merge request. Here is an example: ``` 0024:trace:file:WriteFile 00000010 00490545 9 0122E230 00000000 0024:trace:file:NtWriteFile (0x10,(nil),(nil),(nil),0x122e1e8,0x490545,0x00000009,(nil),(nil)) 0024:trace:server:get_handle_fd( handle=0010 ) 0024:trace:server:get_handle_fd() = BAD_DEVICE_TYPE { type=0, cacheable=0, access=00000000, options=00000000 } 0024:trace:server:write( async={handle=0010,event=0000,iosb=0122e1e8,user=7e4c0020,apc=00000000,apc_context=00000000}, pos=00000000, data={57,69,6e,65,2d,64,62,67,3e} ) trace:server:wake_thread 00d0: *wakeup* signaled=0 0024:trace:server:write() = PENDING { wait=003c, options=00000020, size=0 } 00d0:trace:server:get_next_console_request( handle=0010, signal=0, read=0, status=00000000, out_data={} ) 00d0:trace:server:get_next_console_request() = 0 { code=0050807c, output=00000001, out_size=0, in_data={57,69,6e,65,2d,64,62,67,3e} } 0024:trace:server:select( flags=2, cookie=0021eae4, timeout=infinite, size=8, prev_apc=0000, result={}, data={WAIT,handles={003c}}, contexts={} ) 0024:trace:server:select() = PENDING { apc_handle=0000, signaled=0, call={}, contexts={} } ``` -- v4: server: use TRACE* macros instead of fprintf(stderr) https://gitlab.winehq.org/wine/wine/-/merge_requests/9835
