[PATCH v9 0/3] MR10603: win32u/freetype: Fix tmExternalLeading for CFF fonts.
by Arie Miller (＠Arimil) April 20, 2026

April 20, 2026

This fixes font scaling issues with CFF fonts this was discovered from games utilizing DxLib. https://github.com/yumetodo/DxLib/tree/master https://dxlib.xsrv.jp/index.html I've ran tests on Windows and to confirm that this change is consistent with a number of fonts. Before: ![image.png](/uploads/a398d5543df8561f1a6fbe9edded3b45/image.png){width="801" height="600"} After (this matches the windows visual from testing in a VM): ![image.png](/uploads/cf4e4c8753b3482dd24211b519a5fe23/image.png){width="767" height="572"} Related Proton Issue: https://github.com/ValveSoftware/Proton/issues/7299 Full Disclosure: An LLM was used to assist in finding this bug, the original fix written by the LLM wrote a loader binary that changed the pointers for `GetTextMetricsA` and `GetTextMetricsW` to point to a custom implementation that always set `tmExternalLeading`. The LLM determined that `GDI returns 0 when (winAscent + winDescent) > (Ascender - Descender)`, after testing on WIndows I found this to be incorrect, the actual difference is that CFF fonts always set `tmExternalLeading` to 0. ~~The test case for this fix was LLM generated but reviewed and tested on both Windows and Linux by me.~~ Test case: ``` WINEPREFIX=/tmp/wine-font winetricks allfonts WINEPREFIX=/tmp/wine-font ./loader/wine ./dlls/gdi32/tests/i386-windows/gdi32_test.exe ``` Patched: ``` font.c:4266: test_CFF_external_leading: tested 51 CFF fonts (0 failures) ``` Unpatched Wine: ``` font.c:4266: test_CFF_external_leading: tested 51 CFF fonts (51 failures) ``` Windows 11: ``` font.c:4266: test_CFF_external_leading: tested 48 CFF fonts (0 failures) ``` -- v9: gdi32: Add test for tmExternalLeading for CFF fonts. https://gitlab.winehq.org/wine/wine/-/merge_requests/10603

[PATCH v5 0/1] MR10600: vbscript: Convert VT_DISPATCH arguments to string in Eval/Execute/ExecuteGlobal.
by Francis De Brabandere (＠francisdb) April 20, 2026

April 20, 2026

For VT_DISPATCH arguments, call the object's default property (DISPID_VALUE) to get a string value instead of returning the object via VariantCopy (Eval) or returning type mismatch (Execute/ ExecuteGlobal). This matches Windows behavior where passing a dispatch object without a default property fails with error 438, and objects with a default property have it invoked to obtain the string to evaluate or execute. -- v5: vbscript: Convert VT_DISPATCH arguments to string in Eval/Execute/ExecuteGlobal. https://gitlab.winehq.org/wine/wine/-/merge_requests/10600

[PATCH v21 0/3] MR10464: vbscript: Return "Name redefined" error for duplicate declarations.
by Francis De Brabandere (＠francisdb) April 20, 2026

April 20, 2026

When a name is defined twice (Const/Const, Dim/Const, Const/Dim, Dim/Dim, Sub vs Const/Dim, Class vs Const/Dim/Function, duplicate class members), Windows returns VBScript error 1041 ("Name redefined"). Wine was returning E_FAIL. Store source locations in const_decl_t, dim_decl_t, function_decl_t, and class_decl_t so errors point to the duplicate name. Also fix duplicate Sub/Function/Property/Dim detection inside classes, including the case where a Property collides with an existing Sub/Function. -- v21: vbscript: Return "Name redefined" error for duplicate class members. vbscript: Return "Name redefined" error for duplicate global declarations. vbscript: Track source location in const, class, and function declarations. https://gitlab.winehq.org/wine/wine/-/merge_requests/10464

[PATCH v4 0/4] MR9775: gdiplus: Move X position calculation to callbacks.
by Dmitry Timoshkov (＠dmitry) April 20, 2026

April 20, 2026

An application I'm working on does GdipMeasureCharacterRanges(graphics, "1", 1, ..., 2, regions); GdipGetRegionBounds(regions[0], graphics, &bounds); GdipSetClipRegion(graphics, regions[0], CombineModeReplace); GdipDrawString(graphics, graphics, "1", 1, ..); which leads to an almost completely clipped text output. Attached test application graphically shows the results of bounding boxes calculated by GdipMeasureCharacterRanges(), GdipMeasureString() and GdipDrawString(). This patchset makes the resulting image look closer to what is observed under Windows.

[PATCH v2 0/1] MR10496: vbscript: Return error 1045 for non-literal constant expressions.
by Francis De Brabandere (＠francisdb) April 20, 2026

April 20, 2026

When a Const declaration uses a non-literal expression (e.g. "Const x = 1 + \"a\""), Windows parses the full expression and then rejects it with error 1045 ("expected literal constant"). Change ConstDecl to accept Expression instead of ConstExpression, and validate in new_const_decl() that the expression is a literal or negated numeric literal. Remove the now-unused ConstExpression rule. This fixes both the error code (was generic E_FAIL/16389) and the error character position (now points to the end of the expression). -- v2: vbscript: Return error 1045 for non-literal constant expressions. https://gitlab.winehq.org/wine/wine/-/merge_requests/10496

[PATCH 0/2] MR10702: wscript: Implement WScript.Timeout and //T:nn
by Francis De Brabandere (＠francisdb) April 20, 2026

April 20, 2026

Wires up the WScript.Timeout property and its command-line counterpart //T:nn, both of which were no-op stubs. Commit 1: WScript.Timeout property + //T:nn parsing. Default 0, negative values rejected with VBScript error 5 (matches Windows). //T:nn sets the same value, readable from the script. Commit 2: Actual expiry. A timer thread is armed when Timeout > 0 (from either entry point). On expiry it prints the standard native message to the console and exits with code 1. Setting Timeout to 0 or re-assigning mid-script cancels/re-arms the timer. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10702
