[PATCH 0/3] MR10813: d2d1: Three arc-handling bug fixes (Wine-Bug 59718)
by Giang Nguyen (＠giang17) May 4, 2026

May 4, 2026

This series fixes three independent correctness issues in the d2d1 arc Bezier-approximation code, all reported in Wine-Bug 59718: 1. d2d_arc_to_bezier(): degenerate-radius fallback uses uninitialized points[0] as the line endpoint (introduced in 5d093518d). 2. d2d_arc_to_bezier(): typo in arc center translation, m._12 * center.x where center.y is intended (introduced in 5d093518d). 3. d2d_arc_transform(): radii are direction vectors and should be transformed with the linear part of the matrix only; the current code includes the translation, yielding wrong lengths whenever the transform has a non-zero translation (introduced in c34a09e285). The three commits are independent and can be applied in any order. No tests included — all three are clearly verifiable by inspection, but happy to add specific test cases for any of them if useful.

[PATCH 0/2] MR6841: wow64: Support running a BT module provided suspend routine.
by Billy Laws (＠bylaws) May 4, 2026

May 4, 2026

Suspension in JITs cannot easily be handled on the unix side, so allow BT modules to provide their own suspend helper. This purely supports local thread suspension currently. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/6841

[PATCH 0/1] MR10812: vbscript/tests: Cover bare match.SubMatches(N) indexing.
by Francis De Brabandere (＠francisdb) May 4, 2026

May 4, 2026

Existing regexp.vbs tests only access submatches via the split form (Set submatch = match.SubMatches; submatch.Item(N)) or the chained-call form match.SubMatches()(N). The bare property-then-index form match.SubMatches(N) was untested. Add two assertions on a known pattern to lock in the current behavior. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10812

[PATCH v4 0/3] MR10672: win32u: Initialize Uniscribe fallback registry keys on startup.
by समीरसिंह Sameer Singh (＠ss141309) May 4, 2026

May 4, 2026

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=27641 @aricstewart I thought about the trade-offs between the two approaches (this and https://gitlab.winehq.org/wine/wine/-/merge_requests/10630) and finally decided to go through with this, because this would allow for a more better UX. How does this look? If it looks better, we can close the previous MR. Also I will open a separate MR for the script tag, which will hopefully have a better solution than just using one script tag for a script. -- v4: gdi32/uniscribe: Update font fallback mechanism. https://gitlab.winehq.org/wine/wine/-/merge_requests/10672

[PATCH v2 0/1] MR10805: Draft: msvcrt: only convert _tolower_l if not exact match already
by Stephan Seitz (＠theHamsta) May 4, 2026

May 4, 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. -- v2: msvcrt: only convert _tolower_l if not exact match already https://gitlab.winehq.org/wine/wine/-/merge_requests/10805

[PATCH v10 0/2] MR10753: ntdll/actctx: Add privatePath probing functions in SxS loader
by Bolan Chen (＠bolanc) May 3, 2026

May 3, 2026

Besides manifest files, SxS Loader can also take a config file similar to CLR apps which can instruct the loader to look for manifests in additional paths. Autodesk installers use this somewhat obscure feature so this probe path will help Autodesk software installer to start. The config file looks like ``` <configuration> <windows> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <probing privatePath="path"/> </assemblyBinding> </windows> </configuration> ``` Microsoft mentions this feature in [application config files doc](https://learn.microsoft.com/en-us/windows/win32/sbscs/application-conf…. -- v10: actctx/tests: add tests ntdll/actctx: add functions read .config file, parse privatePath and use https://gitlab.winehq.org/wine/wine/-/merge_requests/10753
