[PATCH v2 0/3] MR10487: winewayland: Fix display freeze for games that fake-minimize
by Cooper Morgan (＠Cwooper) April 19, 2026

April 19, 2026

CryEngine games (e.g., Hunt: Showdown) fake-minimize during startup in exclusive fullscreen by setting WS_MINIMIZE and moving to (-32000,-32000). The driver sent xdg_toplevel_unset_fullscreen, causing the compositor to respond with a 0x0 configure that the surface never recovered from. - Fix a use-after-release on data-\>rects in wayland_configure_window - Detect WS_MINIMIZE and call xdg_toplevel_set_minimized instead of unsetting fullscreen/maximized - Handle restore by acking the configure and sending SC_RESTORE when the window is at the sentinel position with WS_MINIMIZE set Wine-Bug: http://bugs.winehq.org/show_bug.cgi?id=59577 -- v2: winewayland: Restore minimized windows when compositor sends configure. winewayland: Handle WS_MINIMIZE to suppress incorrect state transitions. winewayland: Fix use-after-release of window rects in configure handler. https://gitlab.winehq.org/wine/wine/-/merge_requests/10487

[PATCH v60 0/1] MR10192: kernelbase: Handle extended length path prefix in GetLongPathNameW
by Vishnunithyasoundhar S (＠svishnunithyasoundhar) April 18, 2026

April 18, 2026

``` Support the \\?\ prefix by skipping it during path resolution while preserving it in the output. Added specific handling for extended UNC paths (\\?\UNC\) to mirror standard UNC behavior, ensuring these paths are treated as network shares and not local devices. Some paths that use the extended length path were filtered out as UNC paths - but not all of them are UNC. There can be UNC path that use extended length path but not all extended length paths are UNC paths. ``` Signed-off-by: Vishnunithyasoundhar S svishnunithyasoundhar(a)gmail.com -- v60: kernelbase: Handle extended length path prefix in GetLongPathNameW https://gitlab.winehq.org/wine/wine/-/merge_requests/10192

Re: [PATCH v2 0/7] MR10688: msxml3: Improvements to setAttribute().
by Bernhard Übelacker (＠bernhardu) April 18, 2026

April 18, 2026

Hello Nikolay, I just wanted to forward a note that some of the recent msxml3 changes may started causing following ASan findings. Unfortunately in the past I was carrying the patch from !9279, but dropped it as it stopped to apply to current git. Therefore I currently cannot say if that is a new issue or if it is caused by recent patches. Since [this gitlab run](https://gitlab.winehq.org/bernhardu/wine/-/jobs/253410#L3065) ASan gets triggered. This run was based on top of [1b13526a5f](https://gitlab.winehq.org/wine/wine/-/commits/1b13526a5fcfa55de…. <details> <summary>ASan details</summary> ``` ==msxml3_test.exe==1616==ERROR: AddressSanitizer: heap-use-after-free on address 0x101f4050e318 at pc 0x6ffff922e8e9 bp 0x7ffffe1ff820 sp 0x7ffffe1ff868 READ of size 8 at 0x101f4050e318 thread T0 #0 0x6ffff922e8e8 in domnode_drop_refs /builds/bernhardu/wine/build64/../dlls/msxml3/node.c:1247:15 #1 0x6ffff922e7d8 in domnode_release /builds/bernhardu/wine/build64/../dlls/msxml3/node.c:1385:11 #2 0x6ffff91eea23 in domdoc_Release /builds/bernhardu/wine/build64/../dlls/msxml3/domdoc.c:449:9 #3 0x00014007a586 in IXMLDOMDocument_Release /builds/bernhardu/wine/build64/include/msxml.h:1584:12 #4 0x00014003bf0f in test_put_nodeTypedValue /builds/bernhardu/wine/build64/../dlls/msxml3/tests/domdoc.c:9047:5 #5 0x00014000114b in func_domdoc /builds/bernhardu/wine/build64/../dlls/msxml3/tests/domdoc.c:16907:5 #6 0x0001400eab42 in run_test /builds/bernhardu/wine/build64/../include/wine/test.h:780:5 #7 0x0001400ea54b in main /builds/bernhardu/wine/build64/../include/wine/test.h:900:12 #8 0x0001400ec7da in mainCRTStartup /builds/bernhardu/wine/build64/../dlls/msvcrt/crt_main.c:70:11 #9 0x6fffffc37b94 in BaseThreadInitThunk (C:\windows\system32\kernel32.dll+0x178027b94) #10 0x6fffffdc0be6 in RtlUserThreadStart (C:\windows\system32\ntdll.dll+0x170050be6) 0x101f4050e318 is located 104 bytes inside of 176-byte region [0x101f4050e2b0,0x101f4050e360) freed by thread T0 here: #0 0x6ffffe82d861 in free /home/runner/work/llvm-mingw/llvm-mingw/llvm-project/compiler-rt/lib/asan/asan_malloc_win.cpp:78:3 #1 0x6ffff922def4 in domnode_destroy_tree /builds/bernhardu/wine/build64/../dlls/msxml3/node.c:1378:5 #2 0x6ffff922e7f8 in domnode_release /builds/bernhardu/wine/build64/../dlls/msxml3/node.c:1387:9 #3 0x6ffff91fcefa in domelem_Release /builds/bernhardu/wine/build64/../dlls/msxml3/element.c:115:9 #4 0x00014007a7e6 in IXMLDOMElement_Release /builds/bernhardu/wine/build64/include/msxml.h:3969:12 #5 0x00014003bf06 in test_put_nodeTypedValue /builds/bernhardu/wine/build64/../dlls/msxml3/tests/domdoc.c:9046:5 #6 0x00014000114b in func_domdoc /builds/bernhardu/wine/build64/../dlls/msxml3/tests/domdoc.c:16907:5 #7 0x0001400eab42 in run_test /builds/bernhardu/wine/build64/../include/wine/test.h:780:5 #8 0x0001400ea54b in main /builds/bernhardu/wine/build64/../include/wine/test.h:900:12 #9 0x0001400ec7da in mainCRTStartup /builds/bernhardu/wine/build64/../dlls/msvcrt/crt_main.c:70:11 #10 0x6fffffc37b94 in BaseThreadInitThunk (C:\windows\system32\kernel32.dll+0x178027b94) #11 0x6fffffdc0be6 in RtlUserThreadStart (C:\windows\system32\ntdll.dll+0x170050be6) previously allocated by thread T0 here: #0 0x6ffffe82da86 in calloc /home/runner/work/llvm-mingw/llvm-mingw/llvm-project/compiler-rt/lib/asan/asan_malloc_win.cpp:98:3 #1 0x6ffff922c969 in domnode_create /builds/bernhardu/wine/build64/../dlls/msxml3/node.c:1053:20 #2 0x6ffff91edd7c in dom_document_create /builds/bernhardu/wine/build64/../dlls/msxml3/domdoc.c:2536:21 #3 0x6ffff9209586 in DOMClassFactory_CreateInstance /builds/bernhardu/wine/build64/../dlls/msxml3/factory.c:246:9 #4 0x6ffffcc31b07 in IClassFactory_CreateInstance /builds/bernhardu/wine/build64/include/unknwn.h:248:12 #5 0x6ffffcc30f29 in CoCreateInstanceEx /builds/bernhardu/wine/build64/../dlls/combase/combase.c:1947:10 #6 0x6ffffcc30526 in CoCreateInstance /builds/bernhardu/wine/build64/../dlls/combase/combase.c:1736:10 #7 0x00014007a1d9 in _create_object /builds/bernhardu/wine/build64/../dlls/msxml3/tests/domdoc.c:1207:10 #8 0x00014003a1f5 in test_put_nodeTypedValue /builds/bernhardu/wine/build64/../dlls/msxml3/tests/domdoc.c:8860:11 #9 0x00014000114b in func_domdoc /builds/bernhardu/wine/build64/../dlls/msxml3/tests/domdoc.c:16907:5 #10 0x0001400eab42 in run_test /builds/bernhardu/wine/build64/../include/wine/test.h:780:5 #11 0x0001400ea54b in main /builds/bernhardu/wine/build64/../include/wine/test.h:900:12 #12 0x0001400ec7da in mainCRTStartup /builds/bernhardu/wine/build64/../dlls/msvcrt/crt_main.c:70:11 #13 0x6fffffc37b94 in BaseThreadInitThunk (C:\windows\system32\kernel32.dll+0x178027b94) #14 0x6fffffdc0be6 in RtlUserThreadStart (C:\windows\system32\ntdll.dll+0x170050be6) SUMMARY: AddressSanitizer: heap-use-after-free /builds/bernhardu/wine/build64/../dlls/msxml3/node.c:1247:15 in domnode_drop_refs ``` </details> -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10688#note_137020

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=58900 Bug 58900 This series implements restricted WinRT error handling in combase and\ adds conformance tests for the new behavior. Implemented APIs include restricted error creation / retrieval,\ error context capture, transform, matching, and unhandled error reporting\ paths. Tests were added under dlls/combase/tests and pass locally.\ The existing combase tests also continue to pass. -- v6: combase/tests: Temporarily trim restricted error handling coverage. https://gitlab.winehq.org/wine/wine/-/merge_requests/10659

[PATCH v8 0/3] MR10603: win32u/freetype: Fix tmExternalLeading for CFF fonts.
by Arie Miller (＠Arimil) April 18, 2026

April 18, 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) ``` -- v8: gdi32: Add test for tmExternalLeading for CFF fonts. https://gitlab.winehq.org/wine/wine/-/merge_requests/10603
